摘要
The frequencies for thirty one far-infrared laser emissions, generated by an optically pumped molecular laser with either (CD3OH)-C-13 or CH3 (OH)-O-18 as its laser medium, have been measured for the first time. The frequencies, ranging from 0.443 to 3.243 THz, were measured with a heterodyne technique to a one-sigma fractional uncertainty no less than +/- 5 parts in 10(7). Approximately half of the frequencies measured during this investigation have been used to either confirm or propose new spectroscopic assignments associated with these methanol isotopologues.
