✦ Synopsis

The microwave spectrum of phenyl cyanate was observed in the frequency ranges (15-18) and (30-40 \mathrm{GHz}). Rotational constants were obtained for the ground and first eight excited states of the torsional vibration of the cyanate group with respect to the phenyl ring. The values of the inertia defect indicate the planar equilibrium conformation of phenyl cyanate. The torsional frequency was (42 \mathrm{~cm}^{-1}) estimated from the inertia defects. The torsional motion of the (\mathrm{OCN}) group in this molecule is discussed. ⑲93 Academic Press, Inc.

The potential energy surface and the kinetic parameters for the torsion and wagging vibration modes in methylamine electronic ground state are determined by the RHF/MP2 approximation using a 6-31G//(3df,3pd) basis set. The numerical results are fitted, as a function of the torsional and wagging angl

The microwave torsional-rotational spectra of gauche CH 3 CD 2 OH and CH 3 CD 2 OD have been identified, assigned, and analyzed up to 70 GHz. From the observed a-and c-dipole transitions, it has been possible to determine the effective rotational coefficients and the gauche tunneling energy of the h
