Paper Abstract

In this work high resolution Fourier transform infrared (IR) spectra corresponding to the OCD-bending, C-O stretching and CH2-rocking bands of methyl alcohol-D1 have been recorded in the range 815-1120 cm-1, at a resolution of cm-1. Analysis of the OCD bending mode transitions yielded identification of quantum numbers involved for far Infrared (FIR) laser lines optically pumped by the 10P(34) and 10P(46) CO2 laser lines. The observed wavenumbers for the OCD bending transitions relevant to the laser assignments are presented. The IR assignments are confirmed by forming close combination loops of observed R, P, and Q branch transitions. The results are in agreement with microwave (MW) analysis.
