✦ Synopsis

The microwave spectroscopy of (\mathrm{CH}{2} \mathrm{DSH}) and (\mathrm{CHD}{2} \mathrm{SH}) has been revisited with the intent of identifying and assigning transitions in the excited torsional states. This effort has been successful, but in the course of the investigation it has been necessary to assign additional ground state lines. A preliminary analysis shows that (V_{3}) is much closer to the (-\mathrm{CH}{3}) value of (444 \mathrm{~cm}^{-1}) for both partially deuterated species than our study of many years ago indicated. Further, the preliminary analysis indicates that the sign of (V{1}) has changed for (\mathrm{CHD}{2} \mathrm{SH}) and is now consistent with that for (\mathrm{CHD}{2} \mathrm{OH}). A large (V_{2}) term of opposite sign keeps the trans level below the gauche levels. The determination of a good, full set of potential energy coefficients will have to await a more rigorous analysis. c. 1993 Academic Press. Inc.

An internal axis method (IAM) has been used to determine the potential energy coefficients V 1 , V 2 , and V 3 to internal rotation in CH 2 DSH and CHD 2 SH. Two torsional differences for the gauche ground states and one torsional difference for the excited states were used to fix the V's. A fourth

The zeroth-order kinetic energy is developed for the vibrating-rotating-internally rotating CH(2)DOH and CHD(2)OH molecules using the general theory of Guan and Quade for the vibration-rotation-large amplitude internal motion interactions in molecules. A T transformation is applied to obtain the nec
