Free jet infrared spectroscopy of (28SiF4)2 in the 10 μm region

The rotation–vibration spectra of 28SiF4 dimer have been studied near the ν3 band of monomer 28SiF4. A well-resolved parallel band has been observed 17.5 cm−1 below the monomer band origin. Two perpendicular bands, separated by 2.0 cm−1 and located 4.3 cm−1 above the origin for the lower component,...

Description
Summary:The rotation–vibration spectra of 28SiF4 dimer have been studied near the ν3 band of monomer 28SiF4. A well-resolved parallel band has been observed 17.5 cm−1 below the monomer band origin. Two perpendicular bands, separated by 2.0 cm−1 and located 4.3 cm−1 above the origin for the lower component, show equidistant Q-branch peaks as only resolved lines. The observed band structure indicates that the threefold degeneracy of the vibrational motions in SiF4 is all removed. A C2h structure with a pair of SiF bonds in an antiparallel position is proposed.
