The rotational spectrum of the linear chain molecule tricarbon oxide sulfide, OCCCS, was recorded at room temperature between 118 and 179 GHz using a new commercial millimeter-wave spectrometer. The observed transitions were analyzed together with hitherto unassigned transitions from measurements between 78 and 118 GHz. About 1900 rotational transitions of OCCCS in the vibrational ground state and in 13 excited bending states could be assigned, the latter including the eighth, ninth, and tenth excited state of the low-lying bending mode nu(7) as well as the second excited state of the bending mode nu(6). Besides the determination of effective constants for these newly identified vibrational states, our data also served to considerably improve the effective constants for some of the bending states already characterized in previous publications.

使用一台新的商用毫米波光谱仪，在室温下于118至179吉赫兹之间记录了线性链状分子三氧化硫碳（OCCCS）的转动光谱。将观测到的跃迁与此前在78至118吉赫兹之间测量得到的未归属跃迁一同进行了分析。在振动基态以及13个激发弯曲态中，约1900个OCCCS的转动跃迁得以归属，后者包括低能级弯曲模式ν(7)的第八、第九和第十激发态以及弯曲模式ν(6)的第二激发态。除了确定这些新识别出的振动态的有效常数外，我们的数据还显著改进了先前出版物中已表征的一些弯曲态的有效常数。版权所有2000年，学术出版社。
