摘要
根据半刚性转子近似分析了 CH2D2 的两个红外吸收带。它们分别是 2671.67 cm-1 处的 A 型带和 4425.61 cm-1 处的 C 型带。A 型带先前被归为 v 3+v 9,而 C 型带则暂时被归为 v 3+v 6。这种相互作用尚未得到研究。地面振动状态的旋转常数值如下:A 0=4.303 cm-1,B 0=3.504 cm-1,C 0=3.049 cm-1。
Two infrared absorption bands of CH2D2 have been analyzed in the semirigid rotor approximation. These are the A-type band at 2671.67 cm-1 and the C-type band at 4425.61 cm-1. The A-type band has previously been assigned as v3+v9, and the C-type band is tentatively assigned as v3+v6 The upper state of the A-type band is perturbed presumably by the close lying level 2v5. This interaction has not been investigated. The following values were found for the rotational constants of the ground vibrational state: A0=4.303 cm-1, B0= 3.504 cm-1, C0= 3.049 cm-1.
