Title: A new analysis of the OH radical spectrum from solar infrared
    observations.
Authors: Melen, F.; Sauval, A. J.; Grevesse, N.; Farmer, C. B.;
   Servais, Ch.; Delbouille, L.; Roland, G.
Bibcode: 1995JMoSp.174..490M
Altcode:
  The solar spectrum offered the opportunity to discover OH lines with
  high rotational quantum numbers, which do not appear on laboratory
  spectra. On solar absorption spectra, the authors have identified
  about 580 lines, among which about 400 were observed for the first
  time. They belong to pure rotational transitions in the ground state
  (υ = 0→3; J<SUB>max</SUB>″= 48.5), as well as to the (1-0), (2-1),
  and (3-2) vibration-rotation bands (J<SUB>max</SUB>″= 32.5). Previous
  pure rotation, vibration-rotation, and Λ-doubling data sets related
  to the υ = 0 up to 3 levels were fitted simultaneously together with
  this new set of data, in order to obtain a very complete and accurate
  set of molecular constants for the X<SUP>2</SUP>Π ground state.

Title: Concentrations of hydrogen chloride and hydrogen fluoride
    measured during the MAP/GLOBUS campaign of September 1983
Authors: Zander, R.; Roland, G.; Delbouille, L.; Sauval, A. J.;
   Marché, P.; Karcher, F.; Amoudei, M.; Dufour, B.
Bibcode: 1987P&SS...35..665Z
Altcode:
  Within the context of the MAP/GLOBUS campaign of September 1983,
  several trace species have been observed by absorption spectroscopy
  at the two ground stations of the Jungfraujoch, Switzerland (3580
  m altitude) and the Observatoire de Haute-Provence, France (1905 m
  altitude). The results obtained for HCl and for HF, expressed in terms
  of mean integrated columns above these sites are: Jungfraujoch: (2.1 ±
  0.2) E15 mol cm <SUP>-2</SUP> HCl (4.8 ± 0.2) E14 mol cm <SUP>-2</SUP>
  HF Haute-Provence: (2.6 ± 0.2) E15 mol cm <SUP>-2</SUP> HCl. Taking
  into account the difference in the altitude of the two stations,
  the reported HC1 results are in agreement to within their respective
  uncertainties. The integrated column density of HCl and HF above 11 km
  altitude, deduced from airplane observations on 9 September 1983, are:
  (1.65 ± 0.25) E15 mol cm <SUP>-2</SUP> HCl above 11 km (3.7 ± 1.7)
  E14 mol cm <SUP>-2</SUP> HF above 10 km supporting satisfactorily the
  ground measurements.

Title: The nickel spectrum in the infrared - Application to the
    solar spectrum
Authors: Biemont, E.; Delbouille, L.; Roland, G.; Brault, J. W.
Bibcode: 1986A&AS...65...21B
Altcode:
  The spectrum emitted from a nickel hollow cathode has been recorded
  in the infrared region (1800 &lt; σ &lt; 9000 cm<SUP>-1</SUP>) with
  the National Solar Observatory Fourier transform spectrometer. The
  spectra have been used in order to identify many lines on new high
  resolution solar spectra.

Title: Fourier transform spectrographs.
Authors: Delbouille, Luc
Bibcode: 1986ESOC...24..119D
Altcode: 1986vlt..work..119D
  Fourier-transform spectrograph (FTS) configurations for the ESO
  Very Large Telescope (VLT) are discussed. The advantages of FTSs
  over grating spectrographs are reviewed, including large throughput,
  minimum line distortion, photometric accuracy, wavelength calibration,
  instrumental flexibility, and the 'multiplex' advantage; the application
  of state-of-the-art array detectors to FTSs is also considered. A
  scaled-up version of the FTS for the 4-m Mayall telescope at KPNO (Hall
  et al., 1979), with a 2-m-focal-length collimator and 30-cm cat's-eye
  retroreflectors, is briefly characterized. It is suggested that such
  an FTS be evaluated as a preliminary design for the VLT instrument.

Title: Identification on chromium lines in the infrared solar spectrum
    based on new interferometric measurements
Authors: Biemont, E.; Delbouille, L.; Roland, G.; Brault, J. W.
Bibcode: 1985A&AS...61..185B
Altcode:
  High resolution spectra of chromium obtained by the interferometric
  method show the presence of several hundreds of new lines in the
  infrared region (1800 &lt; V &lt; 9000 cm<SUP>-1</SUP>). These spectra
  have been used in order to proceed to the identification of many
  weak lines on the high resolution solar spectra obtained recently by
  Delbouille et al. (1981).

Title: An investigation of iron in the infrared solar spectrum based
    on FTS laboratory measurements
Authors: Biemont, E.; Roland, G.; Delbouille, L.; Brault, J. W.
Bibcode: 1985A&AS...61..107B
Altcode:
  The application of new high-resolution laboratory data for iron,
  covering the region 1800 to 9000/cm, to the identification of many
  weak lines on high signal-to-noise-ratio solar photospheric spectra,
  is discussed. The spectra emitted by iron hollow cathodes with three
  different carrier gases (He-Ne-Ar) are recorded with the Fourier
  transform spectrometer on Kitt Peak. Comparisons between the spectra
  of iron and the spectra of nickel and of chromium recorded with the
  same carrier gas and between the iron spectrum and the KPNO solar
  spectrum drawn at the same scale are considered. The results are
  presented in tables.

Title: The Interest of Simultaneous Spectral and Spatial High
    Resolution Spectroscopy in the Infrared
Authors: Delbouille, L.; Grevesse, N.; Sauval, A. J.
Bibcode: 1985LNP...233..108D
Altcode: 1985hrsp.proc..108D
  Up to the present, small scale structures on the sun have mostly been
  studied through observations made in the visible and ultraviolet. After
  having recalled some of the main advantages of infrared observations,
  the authors give a few samples of high spectral resolution/low noise
  solar spectra now routinely obtained in this spectral range by using
  Fourier transform spectrometers. The authors then show that such high
  spectral resolution spectra could be obtained in short period of time
  and for small scale solar structures, using a LEST type collector.

Bibcode: 1982A&A...108..201B
Altcode:
  Lines of the C<SUB>2</SUB> Phillips system have been successfully
  searched for on new tracings of high resolution solar spectra. From a
  rather large number of lines of the (0,0), (1,0), and (0, 1) bands,
  we derive empirical values for the band oscillator strengths:
  f<SUB>00</SUB> = 1.41 10<SUP>-3</SUP>, f<SUB>10</SUB> = 1.38
  10<SUP>-3</SUP>, and f<SUB>01</SUB> = 1.12 10<SUP>-3</SUP>. These
  solar f-values are discussed in section 3.1 and compared with recent
  laboratory data. <P />For the Ballik-Ramsay system, only a few
  unblended solar lines have been available, from which we deduced 0.6
  10<SUP>-3</SUP> ≪ f<SUB>00</SUB> ≪ 1.2 10<SUP>-3</SUP>.

Title: f-values for Tb  ii and a search for terbium in the solar
    photosphere
Authors: Biemont, E.; Roland, G.; Delbouille, L.
Bibcode: 1981SoPh...71..223B
Altcode:
  Oscillator strengths have been obtained for the first time for 12
  transitions of Tb II. Solar implications based on these f-values and
  on recent hyperfine structure data are discussed. More especially,
  a detailed investigation of a weak absorption feature located around
  λ 3658 is presented.

Title: Confirming the presence of hydrofluoric acid in the upper
    stratosphere
Authors: Zander, R.; Roland, G.; Delbouille, L.
Bibcode: 1977GeoRL...4..117Z
Altcode:
  Infrared solar observations made by balloon at 27.9 km altitude in April
  1976, and from the ground station of the Jungfraujoch, Switzerland, in
  October 1976, have confirmed the presence of hydrofluoric acid in the
  upper stratosphere. An average value of (3.6 ± .7) × 10<SUP>-10</SUP>
  ppv has been deduced for the concentration of HF above 27.9 km. The
  comparison between the ground-and the balloon observations tends to
  indicate that over 50% of the total atmospheric HF is located above
  25 km altitude.

Title: High Resolution Spectra of the Sun
Authors: Delbouille, L.; Roland, G.
Bibcode: 1969RSPTA.264..171D
Altcode:
  The University of Liege has operated, since 1958, a laboratory of solar
  spectroscopy at the International Scientific Station of the Jungfraujoch
  (Switzerland). During recent years, much effort has been devoted in two
  main directions: (a) techniques of correction for the effects of the
  instrumental function to obtain the best possible knowledge of central
  intensities and profiles of photospheric lines; (b) increase of the
  signal to noise ratio in the records in order to detect and measure
  very faint absorption features. In addition, a balloon-borne equipment
  is now under construction in Liege to observe, with maximum resolution,
  the near infrared solar spectrum from an altitude of about 80 000 ft.

Title: Project to Map the Sky in the Infrared from an

Altcode:
  One of the experiments installed in the TD 1 E.S.R.O. satellite
  (expected launching date 1970), will be devoted to a mapping of the
  sky in the lead sulphide region. The scanning will be obtained by
  the motion of the satellite itself, so a relatively simple infrared
  photometer will be used.

Title: A New Determination of the C^{12}/C^{13} Isotopic Abundance
    Ratio in the Solar Photosphere
Authors: Herzberg, Luise; Delbouille, L.; Roland, G.
Bibcode: 1967ApJ...147..697H
Altcode:
  The XX38743875 A region of the solar spectrum is re-examined for the
  occurrence of lines of the 0-0 band of the ultraviolet system of the
  C13N isotopic molecule. Although the well-known solar line X3874 341 A
  is in excellent wavelength agreement with the P(58) line measured in
  the laboratory, the P(57) line that should also occur in a window in
  the solar spectrum is found to be absent. It is, therefore, concluded
  that the wavelength agreement in the case of the F(58) line is spurious
  and that no lines of C11N are observed. From this, a lower limit R 40
  for the C12/C13 abundance ratio in the photosphere is obtained.

Title: A New Determination of the 12C/13C Abundance Ratio in the
    Solar Photosphere.
Authors: Delbouille, L.; Herzberg, Luise; Roland, G.
Bibcode: 1966AJ.....71Q.383D
Altcode:
  There are at present in the literature two different values for
  the photo spheric abundance ratio 12C/13C, derived from different
  interpretations of the 3874 A region of the solar spectrum. This region,
  as Greenstein, Richardson, and Schwarzschild (Publ. Astron. Soc. Pacific
  62, 15, 1950) have suggested, is the only region where there are
  suitable windows for the observation of lines of C13N [P(58), A3874.345A
  and P(57), A3874.922 A of the 0,0 ultraviolet band]. Greenstein et
  al. could not detect lines of 13CN, and from their absence and the
  fact that in the windows the solar centinuum is approached within 3 %
  derived a lower limit R=36 for the 12C/13C ratio. In contrast, Righini
  (Liege Colloq. 1956, p. 265; Ric. Sci. Rev. 3, 145, 1963) obtained
  R=104 on the assumption that the known weak 3874.358 A Zr+ line is
  blended with the 13CN, P (58) line. Correction of a trivial error in
  the equivalent width reduces his value to 10~, leaving a discrepancy
  by more than a factor 10 between the results. We have re-examined the
  question with solar spectra of higher resolution than obtained before,
  and with new laboratory spectra kindly provided by A. E. Douglas. We
  confirm the coincidence of the P (58) 13CN line with the Zr+ line at
  x3874.358 A. However, near the predicted position of the P (57) line
  A3874.923 A we find only one new line at A3874.99 A. The wavelength
  difference of 0.07 A is too large for identification of this line as
  13CN. We therefore conclude that the coincidence between the solar
  line at 3874.358 A and the 13CN, P(58) line is spurious, and that even
  the new high-resolution spectra do not show lines of 13CN. From this
  we arrive at a lower limit R 40, essentially confirming the value of
  Greenstein et al.
