Abstract The energy levels υ 4 =1, υ 4 =2, and υ 4 =3 of DCCI have been analyzed by using the fundamental ν 4 1 (470–520 cm −1 ) and the overtone 2ν 4 0 (955–1005 cm −1 ) bands together with the hot bands 2ν 4 0,2 ←ν 4 1 , 3ν 4 1,3 ←2ν 4 0,2 , and 3ν 4 1 ←ν 4 1 . In the case of HCCI the previously studied hot bands connected to ν 4 have been completed by adding 3ν 4 1 ←ν 4 1 into the analysis. The various l -type resonances have been taken into account in the analyses of both the isotopomers. Furthermore, the Coriolis resonance between the close-lying ν 3 and ν 4 of DCCI has been considered. Altogether, accurate values for the molecular constants and the resonance parameters have been obtained from simultaneous analysis and they have been compared with those from separate analyses for different levels.

基于红外光谱同时分析HCCI和DCCI的旋振级υ4=1、2、3

摘要 利用基频 ν 4 1 (470–520 cm -1 ) 和泛音 2ν 4 0 (955–1005 cm) 分析了 DCCI 的能级 υ 4 =1、υ 4 =2 和 υ 4 =3 −1 ) 带与热带 2ν 4 0,2 ←ν 4 1 , 3ν 4 1,3 ←2ν 4 0,2 和 3ν 4 1 ←ν 4 1 。在 HCCI 的情况下，先前研究的连接到 ν 4 的热带已经通过将 3ν 4 1 ←ν 4 1 添加到分析中来完成。在两种同位素的分析中都考虑了各种 l 型共振。此外，已经考虑了 DCCI 靠近的 ν 3 和 ν 4 之间的科里奥利共振。总之，分子常数和共振参数的准确值是从同时分析中获得的，并将它们与不同水平的单独分析的值进行了比较。
