Infrared Spectra and Molecular Structures of SiH3F, SiH3Cl, and SiH3Br

Abstract

The structure of the e-type fundamentals of SiH3F, SiH3Cl, and SiH3Br has been resolved and analyzed. The values of the small amount of inertia thus obtained has been combined with microwave measurements to yield the dimensions of the SiH3 group in these molecules. It is shown that the differences in the structure of the SiH3 group are probably within experimental error. Several revisions have been made in the vibrational assignments for SiH3F and SiH3Cl.
