Paper Abstract

Methyl alcohol and its isotopes are the most common and efficient medium for far infrared laser generation. The usual pump source is the regular 12CO2 laser. By using other CO2 isotope lasers it is possible to excite other absorption transitions which can produce new FIR laser lines and also help in understanding fine details of the spectroscopy of methanol molecule. In this work we have pumped 13CD3OH with 13CO2 laser lines for the first time and have also reinvestigated the 12CD3OH molecule. Six new FIR laser emissions were observed. Based on previously known molecular parameters, and Fourier-Transform data we propose tentative assignments for three of the observed FIR lines in 12CD3OH.
