Abstract

A large number of rotational transitions of 32S16O2, 34S16O2, and 32S18O16O have been measured in the mm-, submm-, and terahertz ( approximately 1 THz) spectral regions. These data sets have been combined with all previously measured SO2 microwave and selected far infrared data to obtain a highly precise set of ground state rotational constants for these isotopomers. The rotational constants for the three isotopomers are in MHz as follows: Parameter32S16O234S16O232S18O16O A60778.54977 (44)58991.18295 (51)59101.1690 (27) B10318.07348 (7)10318.50993 (9)9724.64284 (56) C8799.703399 (70)8761.302481 (97)8331.56018 (51) Centrifugal distortion constants up to P10 are included in the fit. A frequency listing of all the data used in the frequency range between about 7 GHz and 1 THz is included. Copyright 1998 Academic Press.

摘要

在毫米波、亚毫米波和太赫兹（约1太赫兹）光谱区域测量了大量32S16O2、34S16O2和32S18O16O的转动跃迁。这些数据集已与所有先前测量的SO2微波数据和选定的远红外数据相结合，以获得这些同位素异构体基态转动常数的高精度数据集。这三种同位素异构体的转动常数以MHz为单位，如下所示：参数32S16O2 34S16O2 32S18O16O A 60778.54977（44）58991.18295（51）59101.1690（27）B 10318.07348（7）10318.50993（9）9724.64284（56）C 8799.703399（70）8761.302481（97）8331.56018（51）拟合中包含高达P10的离心畸变常数。包含了在约7GHz至1太赫兹频率范围内使用的所有数据的频率列表。版权所有1998年学术出版社。
