CH-Bindungsmomente und IR-Intensität von Benzol-Derivaten—IV. CH-Valenzschwingungen 2-, 3- und 4-substituierter Pyridinderivate
Intensity measurements of the CH-stretching vibrations of 40 monosubstituted pyridine derivatives show that also for pyridine derivatives there exists a functional relation between the intensities and the Taft substituent parameters σI. The interpretation of these facts leads to conclusions concerning the polarity of the CH bond moments of the investigated pyridine derivatives. We also discussed the influence of the hetero—N—atom on the CH bond moments.
