Free jet infrared spectroscopy of SiF4-rare gas complexes

The rotation-vibration spectra of 28SiF4-Ar and 28SiF4-84Kr complexes have been studied in the 10 μm region. The triply degenerate ν3 (F2) band of SiF4 reduces to nearly degenerate parallel (A) and perpendicular (E) band of the complex with the C3v structure. The two bands coupled by an A−E Coriolis...

Description
Summary:The rotation-vibration spectra of 28SiF4-Ar and 28SiF4-84Kr complexes have been studied in the 10 μm region. The triply degenerate ν3 (F2) band of SiF4 reduces to nearly degenerate parallel (A) and perpendicular (E) band of the complex with the C3v structure. The two bands coupled by an A−E Coriolis interaction have been analyzed simultaneously. No splitting due to internal motion has been observed. Band shifts by the formation of the complex are discussed in conjunction with the magnitudes of A−E splitting.
