Vibration Spectra of 1,3,5-Triamino-2,4,6-trinitrobenzene

Abstract
Using Wilson's GF matrix method a normal coordinate analysis of the triamino‐trinitrobenzene molecule is made and the Urey–Bradley force field is obtained. Inelastic neutron spectrum is obtained by the time‐of‐flight method and the frequency distribution is calculated in the one phonon and cubic approximation. Group frequency assignments are made and discussed.
