The Microwave Spectrum of Methyl Selenocyanate (CH3SeCN)

Abstract

The microwave spectrum of methyl selenocyanate has been observed for the isotopic species 12CH3 80Se12C14N, 12CH3 78Se12C14N, 12CH3 77Se12C14N, 12CH3 76Se12C14N, 12CH3 82Se12C14N, 13CH3 80Se12C14N and 13CH3 78Se12C14N. For the main isotopic species, a full centrifugal distortion analysis is reported and internal rotation splittings have been analysed for the ground and first excited torsional states, and also for the ν10 = 1 and ν10 = 2 excited vibrational states. A structure based on a mixture of rs and ro arguments is reported, and also the principal components of the dipole moments.
