Abstract

High-resolution FTIR spectra of the weak CD₃-rocking bands of CD₃OH and ¹³CD₃0H have been obtained. These bands lie below the strong C-0 stretching bands, and show a rather different structure. Numerous P, Q and R branch series have been assigned, from which the branch origins have been determined. The structure of the bands and the separation of n=0 and n=l branch origins indicate a substantial increase of about 31% in the torsional barrier height V3 from the ground to the CD₃-rock states, but the usual energy level model does not appear to reproduce the observed branch origin patterns.
