C-13 METHANOL FAR-INFRARED LASER - NEWLY DISCOVERED LINES, PREDICTIONS, AND ASSIGNMENTS

We report 25 new laser lines from (CH3OH)-C-13 methanol when pumped by a cw CO2 laser. The majority of the lines are pumped by the 10R (regu lar) and 10SR (sequence) bands of the CO2 laser. Two are pumped by the 9HP(20) hot-band CO2 line. We measured 22 laser frequencies in this m olecule, 19 from new lines and three from previously reported lines. W e also remeasured and corrected the frequency of the 9P(44) pumped lin e as 3 378 404.87 MHz (88.738 mu m). We assigned two lines-10SR(17), 7 7.5758 cm(-1) and 10R(50), 119.3020 cm(-1)-and predicted other potenti al far-infrared laser lines with these two pumps. (C) 1998 Academic Pr ess.
