✦ Synopsis

We report 25 new laser lines from 13 CH 3 OH methanol when pumped by a cw CO 2 laser. The majority of the lines are pumped by the 10R (regular) and 10SR (sequence) bands of the CO 2 laser. Two are pumped by the 9HP(20) hotband CO 2 line. We measured 22 laser frequencies in this molecule, 19 from new lines and three from previously reported lines. We also remeasured and corrected the frequency of the 9P(44) pumped line as 3 378 404.87 MHz (88.738 mm). We assigned two lines-10SR(17), 77.5758 cm 01 and 10R(50), 119.3020 cm 01 -and predicted other potential farinfrared laser lines with these two pumps.
