Triazoles. Part X. Hydrogen bonding and infrared spectra
Abstract
I.r. spectra of N-unsubstituted 1,2,4-triazoles in the 1700–3000 cm.–1 region have been studied, and classified according to the intensity and number of bands characteristic of strong intermolecular hydrogen bonding. Evidence of groups showing different degrees of proton tunnelling is advanced; one of these groups appears to be involved in phosphorescent effects.
