A BWO-based terahertz spectrometer has been constructed and tested by measuring some high-J rotational transitions of NNO in the frequency region from 620 to 730 GHz. The observed line center frequencies confirm the previously reported ones obtained by FTIR spectroscopy. The high sensitivity of the present spectrometer allowed us to record spectra of singly substituted isotopomers, 15NNO, N15NO, NN18O, and NN17O, in natural abundance. The rotational and centrifugal distortion constants have been revised. Copyright 1997 Academic Press. Copyright 1997Academic Press
已构建了一台基于返波管振荡器的太赫兹光谱仪，并通过测量NNO在620至730GHz频率范围内的一些高J转动跃迁进行了测试。观测到的谱线中心频率证实了先前通过傅里叶变换红外光谱法获得的结果。本光谱仪的高灵敏度使我们能够记录天然丰度下单取代同位素异构体15NNO、N15NO、NN18O和NN17O的光谱。转动常数和离心畸变常数已得到修正。版权所有1997年学术出版社。版权所有1997年学术出版社
