Experimental and theoretical study of the IR absorption spectrum of 2,4-oxazolidinedione

Abstract

The IR absorption spectra of 2,4-oxazolidinedione in tablet and solution form were measured over the frequency range 400–3600 cm−1. The complete set of normal modes for the molecule are calculated on the basis of a mechanical model with symmetry Cs. The spectrum is interpreted. The spectral features can be explained by taking into account the strict Cs symmetry of the molecule as a whole and the approximate C2v symmetry with traces of D5h for the ring.
