Abstract
Assignment of the normal vibrations of 5-chloro-, 5-bromo-, 5-methyl-, and 2-methylpyrimidines was made through the vibrational analyses of the polarized Raman and infrared spectra and also through the normal coordinate calculation. The normal vibrations of 5-halo- and 5-methylpyrimidines were compared with those of 2-halo- and 2-methylpyrimidines, and a substitutional effect on the vibrational frequencies and modes of the hydrogen bending and wagging vibrations was studied.
