Abstract

Structure, intensity and depolarization ratio of NH or NH~2~ Raman bands of some primary and secondary amines have been studied in pure liquid state at different temperatures and in dilute CCl~4~ solutions. The depolarization ratio and scattering activity, as in the case of alcohols previously studied, increase with self association. It confirms the change of the XH bond polarizability derivatives with hydrogen bond formation.

Raman spectra have been recorded for d,,, d , and ds pivalic acids and pivalic anhydride in the liquid phase and in solution in CC14. A complete assignment of the bands is proposed and discussed specially in relation to dimerization and eventual breaking of dimers. The potential energy for hindered
