The Fourier transform infrared spectrum of the 6 and 2 9 bands of deuterated formic acid (HCOOD) was recorded with an apodized resolution of 0.004 cm Ϫ1 in the frequency range of 930 -1040 cm Ϫ1 . These two bands with band centers 40 cm Ϫ1 apart were mutually coupled by Coriolis and Fermi interactio

✦ Synopsis
The n 6 band of methyl chloride centered near 1018 cm 01 has been recorded with a precise homemade Fourier transform spectrometer. About 5400 lines of this band have been assigned. The ground state constants for both isotopomers, CH 3
35 Cl and CH 3 37 Cl, were obtained from combination differences of the wavenumbers and the upper state constants were deduced from a least-squares fit procedure which permits reproduction of the observed wavenumbers with a standard deviation of 1.1 1 10 04 cm 01 , close to the experimental uncertainty.
