Abstract
Infrared-infrared double-resonance spectroscopy has been carried out for CD3OH. Seven of the observed double resonance signals occur in the congested Q-branch region of the C-O stretch band while one is a transition to an excited torsional state. The signals appear as single signals as opposed to the more regular appearance as pairs. Three of the observed transitions involve excited-state levels which are shifted by Fermi resonance between excited C-O stretch-state levels and levels of high-lying torsional modes of the vibrational ground state. These resonances result in a considerable change in the Stark shift for the excited-state levels compared with unperturbed levels. The a-component μ″ a of the permanent electric-dipole moment value has been determined for several ground-state levels. The average value in the ground state is calculated to be μ″ a =0.918D. The results have allowed the assignment of several previously reported far-infrared laser lines and also confirmed assignments proposed by other workers.
