Vibration Spectra of 1,3,5hyphen;Triaminohyphen;2,4,6hyphen;trinitrobenzene

摘要

Using Wilson's GF matrix method a normal coordinate analysis of the triaminohyphen;trinitrobenzene molecule is made and the Ureyndash;Bradley force field is obtained. Inelastic neutron spectrum is obtained by the timehyphen;ofhyphen;flight method and the frequency distribution is calculated in the one phonon and cubic approximation. Group frequency assignments are made and discussed.
