Abstract
The infrared spectra of sublimed films of cyanuric acid and deutero cyanuric acid, and the polarized spectra of (101) single crystals of cyanuric acid are reported. The active valence fundamentals and the higher frequency bending vibrations have been identified. A characteristic feature of the spectrum is the occurrence of several doublet bands which represent pairs of vibrations whose degeneracy is removed in the potential field of the crystal. The splitting of the carbonyl frequency is very small which is taken to indicate the near equivalence of all C=O bonds in the molecule. The splitting of N-H valence vibrations is large indicating the presence of two considerably different hydrogen bonds. These results are in disagreement with the X-ray structure determination of Wiebenga and Moerman, which is believed to be in some error.
