ResumoAbstract The infrared absorption bands of oriented crystal films of 4,6-dichloropyrimidine have been studied at ambient (290–300 K) and low (20–30 K) temperatures. Infrared spectra of the compound have also been recorded as Nujol mulls as well as dilute solutions in carbon tetrachloride and chloroform. Solution phase Raman spectra have been obtained as an aid to the assignment of the crystal bands observed in the infrared spectra. The crystal band splittings have been utilized to deduce the factor group gas C 2v and molecular site symmetry as C s − No X-ray crystallographic study of the compound has been reported in the literature. A complete assignment of the crystal spectrum consistent with the observed splittings and dichroic ratios of bands has been proposed and several previous assignments are revised.
