FAR-INFRARED LASER ASSIGNMENTS AND PREDICTIONS FOR CO-STRETCHING AND CH3-ROCKING STATES OF OPTICALLY PUMPED (CH3OH)-C-13

High-resolution Fourier transform studies of the CO-stretching and CH3 -rocking bands of (CH3OH)-C-13 have been applied to the assignment of far-infrared (FIR) laser transitions optically pumped by CO2 infrared (IR) lasers. The assignments are based on spectroscopic identification of the IR pump transitions at the reported offsets from the CO2 laser lines and agreement between the FIR laser wavenumbers and values calc ulated from IR/FIR combination-loop relations. Wavenumbers are also pr edicted for further potential new FIR laser lines in transition system s that could be pumped by CO2 and (CO2)-C-13 cw and waveguide lasers.
