根据分子对称性、核自旋统计、观察到的选择规则和跃迁双重态的顺序，纯光谱地推导出了CO二聚体一些最低能级的振动归属。Surin等人以前的大多数任务。首页--期刊主要分类--期刊细介绍--期刊题录与文摘--期刊详细文摘内容化学。A111(2007)12238-12247]在本工作中得到了证实，并得到了许多明确证据的支持。在本工作中，对该分析的一个重要修订是识别扭转(平面外)激发态，该激发态先前被指定为齿轮(平面内)内旋转的激发态。
Vibrational assignments for some of the lowest energy levels of the CO dimer have been derived purely spectroscopically on the basis of the molecular symmetry, nuclear spin statistics, observed selection rules, and sequence of the transition doublets. Most of the previous assignments of Surin et al. [L.A. Surin, D.N. Fourzikov, T.F. Giesen, S. Schlemmer, G. Winnewisser, V.A. Panfilov, B.S. Dumesh, G.W.M. Vissers, A. van der Avoird, J. Phys. Chem. A 111 (2007) 12238–12247] are confirmed in the present work, and are supported by much clear evidences. One significant revision of that analysis in the present work is identification of the torsional (out-of-plane) excited state, which had been assigned previously to an excited state of the geared (in plane) internal rotation.
