Transferability of Urey-Bradley Force Constants. VI. The Silyl Halides

Abstract

Urey‐Bradley force constants have been fitted, by least squares, to the observed vibrational frequencies of SiH₃F, SiH₃Cl, SiH₃Br, SiH₃I and their fully deuterated analogs. The force constants have been correlated with other molecular parameters and, in the case of the nonbonded hydrogen‐halogen repulsions, have been discussed in terms of an inverse‐power potential function.
