✦ Synopsis

The infrared spectra of the n 3 and n 9 bands of methylene chloride have been recorded both for isotopically pure CH 2 35 Cl 2 and for a natural mixture with a resolution of 0.0025 -0.004 cm 01 ( FWHM ) in the range 600 -800 cm 01 using 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 for the CH 2 35 Cl 37 Cl isotopic species. An effective coupling constant j c 39 Å 0.1975 ( 2 ) cm 01 results from a full rotational analysis of a difference spectrum, obtained by subtracting the CH 2 35 Cl 2 room temperature spectrum from that of the natural mixture. A least-mean-squares fit of the data to Watson's A-reduction Hamiltonian in the I r representation yields a set of accurate effective rotational and distortion constants up to quartic terms for the excited states of both fundamental bands. The standard deviation of the fit was 0.893 1 10 03 cm 01 .
