Abstract

Measurements have been made on the pressure broadening coefficients of 12CH3OH, -1,5 band. Doppler-free spectra obtained with intermodulated photoacoustic measurements in the pressure range from 7 to 130 Pa yield self-broadening parameters of the strong absorption lines that produce far infrared lasing with optical pumping. The dominant absorption lines in the frequency windows of the CO2 9R(16) and 9R(18) have been re- solved into closely- lying two components separated by 14 MHz.
