✦ Synopsis

The n 2 band of 35 ClNO 2 at 12.6 mm has been studied by high-resolution Fourier transform spectroscopy. Assignments have been made for 1423 a-type rotational transitions. The band center is found to be 792.7613 cm 01 , and rotational and centrifugal distortion constants have been determined. Measurements have also been made of the absorption coefficients of the Q branches of the 35 Cl and the 37 Cl isotopomers of this band. The peak absorption coefficients measured over a range of temperatures from 298 to 205 K showed no measurable dependence on temperature. The average peak absorption coefficient value of the 35 Cl isotopomer was measured to be 8.6(1.0) 1 10 019 cm 2 /molecule and that of the 37 Cl isotopomer to be 3.5(1.0) 1 10 019 cm 2 /molecule.

High-resolution FTIR data of carbonyl fluoride in the region of the C-O stretch n 1 fundamental have been analyzed. Satisfactory interpretation of the spectral data required a rigorous analysis that involved the inclusion of Fermi resonance with the 2n 2 state and Coriolis interaction with the 2n 3
