By utilizing the results of high resolution infrared (IR) and far-infrared (FIR) spectroscopy we discuss the reported assignments of more than 300 FIR laser lines in optically-pumped CH3OH. The analysis has been done both by feeding each IR-pump/FIR-laser transition system into the computer fit program described in previous works, and by combining the CO2 laser optical pumping frequency, the FIR laser frequencies and the IR and FIR spectroscopic measurements to construct closed frequency loops. When the energy balance of a loop is found to be zero to within experimental uncertainty the assignments of all sides of the loop are supported. In addition, improved accuracies by one to two orders of magnitude for the FIR laser frequencies, and predictions for new laser lines have been obtained for a number of systems from loop combination differences.

Abstract

By utilizing the results of high resolution infrared (IR) and far-infrared (FIR) spectroscopy we discuss the reported assignments of more than 300 FIR laser lines in optically-pumped CH3OH. The analysis has been done both by feeding each IR-pump/FIR-laser transition system into the computer fit program described in previous works, and by combining the CO2 laser optical pumping frequency, the FIR laser frequencies and the IR and FIR spectroscopic measurements to construct closed frequency loops. When the energy balance of a loop is found to be zero to within experimental uncertainty the assignments of all sides of the loop are supported. In addition, improved accuracies by one to two orders of magnitude for the FIR laser frequencies, and predictions for new laser lines have been obtained for a number of systems from loop combination differences.
