Abstract

It is proposed that a number of the high-frequency far-infrared (FIR) laser lines observed when CH3OH is optically pumped by high-power CO2 TEA lasers can be identified as refilling torsional transitions within the vibrational ground state. Assignments are presented for 8 such TEA-pump/FIR-laser refilling systems. To provide support for the assigned laser frequencies, high-resolution Fourier transform FIR spectra of CH3OH have been obtained and partially analyzed in the torsional transition region.
