Abstract

Abstract The i.r. spectra of polycrystalline samples of α-, β- γ-glycine-d 0 and the corresponding Cd 2,ND 3 and d 5 deuterated derivatives have been investigated at room temperature as well as at liquid nitrogen temperature. The analysis of the observed frequency shifts between polymorphic glycines has yielded information on the vibrational modes of isotopic derivatives which have the same form. The CH 2 and NH 3 group vibrations have been assigned.
