Jovian Planets

High resolution spectra of Jupiter and Saturn were obtained with a Fourier Transform Michelson interferometer. A comparison of the observed spectra, after elimination of the solar and terrestrial contributions to absorption, with synthetic profiles for the reflecting layer model has permitted new determinations of the Lorentz half-width, the methane abundance, the rotational temperature and the pressure at the level of formation of the methane lines for both Jupiter and Saturn.

A Michelson interferometer was put into operation during the year 1972 at the Coudé focus of the Haute-Provence Observatory’s 76-in. telescope. We built this instrument at Aimé Cotton Laboratory (Orsay-France) where the method of Fourier Transform Spectroscopy has been largely developed in the direction of very high resolution work. A complete description of this device has been given elsewhere (Guelachvili and Maillard, 1970) and further details on the present study are reported by Maillard (1973).

Truncation Function

Digitally recorded spectra containing lines of width less than or equal to the resolution at which the measurement has been made are observed to show some photometric In spectra measured by Fourier transform spectroscopy, this error may be substantially reduced if the interferogram is zero-filled. To prevent the generation of artifacts in the spectrum (of a similar origin to the sine x side-lobes formed when a non-zero-filled spectrum is computed with a box-car truncation function), the zero-filled interferogram must be suitably apodized.

Atmospheric Sounding

The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) instrument which operated on the Envisat satellite from 2002-2012 is a Fourier transform spectrometer for the measurement of high-resolution gaseous emission spectra at the Earth's limb. It operates in the near- to mid-infrared, where many of the main atmospheric trace gases have important emission features. The initial operational products were profiles of Temperature, H2O, O3, CH4, N2O, HNO3, and NO2, and this list was recently extended to include N2O5, ClONO2, CFC-11 and CFC-12. Here we present preliminary results of retrievals of the third set of species under consideration for inclusion in the operational processor: HCN, CF4, HCFC-22, COF2 and CCl4.

Abstract Employing the high resolution of microwave Fourier transform spectroscopy, we investigated the lowest rotational transitions of fluoro-, bromo-, and iodoacetylene-d. Along with the rotational, centrifugal distortion, halogen nuclear quadrupole, and halogen spin-rotation coupling constants, we determined the deuterium quadrupole coupling constants of bromo-and iodoacetylene-d. For fluoroacetylene-d, we redetermined the deuterium nuclear quadrupole coupling constants with higher accuracy.
