✦ Synopsis

The infrared spectra of the n 3 and n 9 bands of isotopically pure CH 35 2 Cl 2 have been recorded at a resolution of 0.0025 cm 01 in the range 600-800 cm 01 with a Bruker IFS 120 HR Fourier Transform interferometer. The Coriolis coupling between the two CCl 2 stretching fundamentals n 3 and n 9 has been investigated. An effective coupling constant j c 3,9 Å 0.20101(3) cm 01 (z c 3,9 Å 0.98) was obtained from a rotational analysis of spectra recorded at room temperature. From relative intensities the ratio of the vibrational transition moments of the fundamentals n 3 and n 9 could be estimated as

and the sign of

ͪ was found to be negative. Excited state constants up to quartic terms have been obtained for both fundamental bands, using Watson's A-reduction Hamiltonian in the I r representation. The standard deviation of the fit was 0.44 1 10 03 cm 01 .

The gas-phase IR spectra of the n 5 , n 3 , n 6 , and n 2 bands of FNO 2 have been studied at resolutions ranging from 0.0023 to 0.0050 cm 01 . These bands form an isolated tetrad which is coupled by a-, b-, and c-Coriolis resonances. The c-Coriolis interaction between n 3 and n 5 is particularly st
