Abstract
A comparison is given between the dipole moments found experimentally for 1, 2, 4-triazole and its derivatives and those computed vectorially. In 1, 2, 4-triazoles unsubstituted on nitrogen, the hydrogen is attached at N1 in the majority of cases. The 1, 2, 4-triazoles undergo acylation on N1. Under the influence of a strong electron acceptor (a p-nitrophenyl substituent), the electron cloud of the triazole ring is highly polarized.
