Abstract

The results of high-resolution Fourier-transform infrared and far-infrared spectroscopic studies have been applied to the analysis and prediction of optically pumped far-infrared laser emission for 11 transition systems of the CD3OH isotopomer of methanol. The assignments are supported by the formation of closed transition combination loops that confirm the spectroscopic assignments and yield calculated far-infrared laser wave numbers to the spectroscopic accuracy of order ±0.0005 cm-1. This represents a substantial improvement over customary wavelength measurements. Four of the systems involve the strong asymmetry mixing known to occur between K=0 and K=2 E1 levels, which is discussed and partially analyzed. Several inconsistencies are noted between previous proposed assignments in the literature, which were based primarily on calculated energies and infrared wave numbers, and our new spectroscopic data.
