Normal-Coordinate Treatment and Computation of Coriolis Coefficients and Ground-State Centrifugal-Distortion Constants of Digermane, Disilane, Methylgermane, and Methylsilane

Abstract

A normal‐coordinate calculation was performed for digermane, disilane, methylgermane, and methylsilane as well as for their deuterated analogs which are of the symmetric‐top type. Vibrational frequencies, Coriolis‐coupling coefficients, and ground‐state centrifugal‐distortion constants were computed using the best set of force constants obtained.
