HIGH-RESOLUTION FOURIER-TRANSFORM AND SUBMILLIMETER-WAVE SPECTROSCOPY OF THE NU-3 AND 2-NU-3 [- NU-3 BANDS OF (CH3F)-C-13

Fourier transform spectra of the ν3 band (up to J ≤ 40, 954-1076 cm-1) and of the 2 ν3 ← ν3 band (up to J ≤ 29, 956-1044 cm-1) of 13CH3F have been measured with 0.002-0.003 cm-1 resolution. Submillimeter-wave spectra of the pure rotational transitions in the v3 = 0 and v3 = 1 vibrational states up to J ≤ 10 (196-550 GHz) have been measured using the submillimeter-wave spectrometer with acoustic detection. Improved sets of spectroscopic parameters have been obtained for the v3 = 0, 1, and 2 vibrational states by fitting simultaneously the Fourier transform and submillimeter-wave data. © 1991.
