| Abstract: | Rotational spectra of 13 carbon chloromethane isotopologues 13CH335Cl and 13CH337Cl with resolved hyperfine structures were measured in the spectral region from 50 GHz to 275 GHz. An estimated uncertainty of individual well developed lines was better than 5 kHz. Ground state molecular parameters B, DJ, DJK, HJ, HJK, HKJ, eQq, and CN were derived. Determination mainly of the hyperfine constants is significantly better than in previous studies. |
