Abstract

We report 25 new laser lines from 13CH3OH methanol when pumped by a cw CO2 laser. The majority of the lines are pumped by the 10R (regular) 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 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 μm). We assigned two lines-10SR(17), 77.5758 cm-1 and 10R(50), 119.3020 cm-1-and predicted other potential far-infrared laser lines with these two pumps. Copyright 1998 Academic Press.

摘要

我们报告了用连续波二氧化碳激光泵浦时，来自(^{13}CH_3OH)甲醇的25条新激光谱线。大多数谱线由二氧化碳激光的10R（常规）和10SR（序列）波段泵浦。两条由9HP(20)热波段二氧化碳谱线泵浦。我们测量了该分子中的22个激光频率，其中19个来自新谱线，3个来自先前报道的谱线。我们还重新测量并校正了9P(44)泵浦谱线的频率为3378404.87 MHz（88.738μm）。我们确定了两条谱线——10SR(17)，77.5758 (cm^{-1}) 和10R(50)，119.3020 (cm^{-1})——并用这两个泵浦源预测了其他潜在的远红外激光谱线。版权所有1998年学术出版社。
