Far infrared laser lines in CH3OH, optically pumped to CO stretch states and to strongly interacting vibrational states
A commented table is presented, containing 90 assigned FIR emission lines of the CH 3 OH laser, which can be dixectly or indirectly related to the torsional ground state of the CO stretch. Based on a model, which empirically takes into account interactions with other vibrational modes, the table com...

Summary: | A commented table is presented, containing 90 assigned FIR emission lines of the CH 3 OH laser, which can be dixectly or indirectly related to the torsional ground state of the CO stretch. Based on a model, which empirically takes into account interactions with other vibrational modes, the table compares measured and calculated pump and emission frequencies. For 14 pump transitions with J \leq 26 , the rms deviation is 0.005 cm -1 . For 26 FIR emission transitions involving J \leq 26 , where the accuracy of the model can be checked against frequency measurements, the rms deviation is 0.004 cm -1 . Pump transitions to a strongly perturbing mode are identified, and accurate energy level parameters for this mode are given. |
