The absorption spectrum of SiH4 from 32 to 400 cm−1 has revealed two sepasrate bonds,one linear in density and one quadratic.From the linear band,the electric dipole moment produced in the ground vibronic state by centrifugal distortion effects has been estimated to be 9.3 × 10−6 D in magnitude. From the quadratic band, the molecular octopole moment has been determined to be 3.0 × 10−34 esu cm3 in magnitude. The simplicity of the techniques used is stressed.
