Abstract
The high-resolution infrared spectrum of CH281BrF has been studied in part of the atmospheric window between 920 and 980cm−1, the region characterized by the v9 and v5+v6 absorptions. The v9 emerges as a pseudo a-type band, with selection rule ΔKa=ΔKc=0, ±2, and v5+v6 exhibits a predominant a-type structure.
The interactions connecting these levels and the dark 3v6 state have been explored. The anomalous v9 transitions have been ascribed to Coriolis interaction with v4. The analysis yields a set of accurate upper-state parameters for v9 and v5+v6. Spectroscopic information on 3v6 has been also obtained.
