Abstract
The millimeter- and submillimeter-wave spectrum of 13CD2F2 present in natural abundance in methylene fluoride-d2 (CD2F2) has been measured in the region 230–380 GHz. The spectrum was recorded using a frequency-modulated millimeter- and submillimeter-wave spectrometer. More than 200 rotational transitions in the ground state of 13CD2F2 with J≤45 and Ka≤8 have been assigned. A combined weighted least squares fit of the newly assigned transitions with previously reported microwave data has been carried out in the Watson's A- and S-reduced Hamiltonian. The data have been fitted with a standard deviation approaching the experimental accuracy, to provide improved values for the rotational and quartic centrifugal distortion constants, including sextic distortion constants for the ground state of 13CD2F2.
