The far infrared spectra of the Q branches of hindered rotation in CH 3OH and CD 3OH have been investigated in the 80-250 cm -1 spectral region. The theoretical spectra are calculated using the full set of Kirtman constants and are compared with experimental spectra of resolutions up to 0.25 cm -1. The theoretical spectrum of CH 3OH is slightly different from previously published data which did not include all of the Kirtman perturbation terms. For both molecules the agreement of the theoretical and experimental spectrum is satisfactory considering that only the Q-branch spectra have been studied. Experimentally, many more lines have been found which most likely belong to P- and R-branch lines or clusters thereof.
