Abstract
The laser Stark spectrum of fully deuterated methanol has been studied using the 337 and 311-μm lines of the HCN laser. Numerous families of absorption lines have been observed for both parallel and perpendicular polarizations up to 60 kV/cm. An extensive series of absorption lines observed at 311 μm has been assigned to the J = 11 to 19 members of the K = 11 ← 10 E 2 Q branch in the v t = 0 ground torsional state of CD 3OD. An R-branch transition observed at 311 μm has been identified as the J K = 11 7 ← 10 6 A, v t = 0 transition. Three families of resonances observed at λ = 337 μm are identified as J K = 18 3 ← 17 2 E 1, v t = 0; J K = 17 3 ← 16 4 E 1, v t = 1; and J K = 9 7 ← 8 6 A, v t = 0, transitions. Zero-field frequencies for all the assigned transitions are given with improved accuracy over those calculated from available molecular constants. For the Q-branch series, the branch origin and the series expansion coefficients are presented.
