Infrared Spectra of Polysubstituted Pyrimidines in the 700–200 cm−1 Region

Abstract
The infrared spectra of 28 substituted pyrimidines are presented in the 700–200 cm−1 region. These compounds are characterized by the in-plane ring deformation mode near 500 cm−1, and the out-of-plane ring deformation near 450 cm−1. The resonance, inductive, and mass effects on these and on other fundamental modes are also presented.
