 Title: SUBMILLIMETER LASER STARK SPECTROSCOPY OF $CD_{3}OH$ WITH THE HCN LASER Creators: Sarker, J. C.; Sudhakaran, G. R.; Mukhopadhyay, Indranath; Bhattacharjee, R. L.; Johnston, L. H. Issue Date: 1989 Publisher: Ohio State University Abstract: A submillimeter laser Stark spectrum of partially deuterated methyl alcohol, $CD_{3}OH$ has been investigated at $\lambda = 311 \mu$m of the HCN laser. The spectrum has been taken up to 60,000 volts/cm in both parallel and perpendicular polarizations. An R-branch K-doublet transition has been observed for the first time and assigned as $J_{k} = 14_{4} \leftarrow 13_{3}, A, v_{t} = 0$, and $J_{k} = 14_{4} \leftarrow 13_{3}, A, v_{t} = 0$ torsional state. Zero-field frequencies of this doublet are reported with an accuracy of about 10 MHz based on the contribution from the K-doublet interaction only. The accuracy should improve up to about 1 MHz when the other nearby levels interaction will be taken into account.
