Calculation and study of the infrared absorption spectrum of 2, 5-dimethyl-4-phenylpyridine

The infrared absorption spectrum of 2, 5-dimethyl-4-phenylpyridine has been recorded in the range 400–2000 cm^–1 and the valence-force scheme has been used to calculate the values of the fundamental frequencies and the forms of the normal vibrations.In conclusion the author thanks M. M. Kusakov for directing the work and L. A. Gribov for discussion of the results.
