Assignments of the high power optically pumped CW laser lines of CH3OH
Abstract
Thirteen far IR laser lines in CH3OH, optically pumped by a CO2 laser, have been assigned to a- and b-type transitions in nu5 CO-stretch band. Identification procedures used were: a frequency match between the CO2 pump and CH3OH absorption, frequency match of laser lines and CH3OH nu5 transitions, polarization of far IR radiation, cascade and competition effects between far IR laser lines, and frequency consistencies. An improved set of molecular constants for nu5 transitions were also obtained.
