Abstract

With the advent of the laser, the far-infrared region has emerged as an area of fertile exploration. This research reports the first investigation into whether the partially deuterated isotopic form of methanol, 13CHD2OH, could serve as a far-infrared laser medium. We are pleased to report the discovery of eight far-infrared laser emissions having wavelengths ranging from 33.8 to 80.9 micron. The frequencies of these laser lines have also been measured and are reported with fractional uncertainties of 3 parts in ten million. Due to the accuracy with which these measurements were made, they will serve as sources of coherent far-infrared radiation for a variety of spectroscopic investigations. One such study includes the investigation of free radicals (e.g. FeD) in the 30 to 80 micron region using laser magnetic resonance spectroscopy.
