摘要: The high‐resolution infrared spectrum of ν5 CH3I reported in the previous paper [J. Chem. Phys. 55, 1787 (1971)] has been reanalyzed. By extending assignment observed lines and by taking account xy‐type Coriolis interaction with ν2 addition to Fermi resonances ν3+ν6, rotational constants have determined be B 5(unp) = 0.250159 cm−1 3,6(unp) 0.247631 which are now consistent microwave results. l‐type doubling constant obtained q 5(unp)=−2.2× 10−5 cm−1. resonance term found depend on quantum number J.
