The infra-red spectra (650-222 cm−1) of some compounds containing the 2-pyridyl group

Abstract

The infra-red spectra (650-222 cm⁻¹) of nine 2-substituted pyridines, including those of four 2-pyridylamines, have been recorded. Solid compounds have been examined as mulls and as chloroform and/or carbon tetrachloride solutions and pronounced solid state effects were noted in one case. Empirical assignments of the major bands have been attempted and it is concluded that ν_6b-α(CCC), ν₁₁-X-sens φ(CC) and ν_16a8φ(CC) may be assigned with some certainty even when the molecular complexity is considerable.
