Abstract
The optically-pumped far-infrared (FIR) laser emission from the $CH_{3}^{18}OH$ isotopomer of methanol is reviewed from the perpectives of accurate heterodyne laser frequency measurements and line assignment utilizing high-resolution Fourier transform infrared (IR) and FIR spectra. The number of observed FIR laser lines has now reached 105 for this species, 22 of which have been measured in frequency. We discuss the available techniques for identifying the IR-pump/FIR-laser energy level and transition schemes, and their application in obtaining the current list of know assignments for 57 laser lines. As well, we present a list of predicted wavenumbers of potential FIR laser lines for future research interest.
