## Abstract ^1^H, ^13^C, ^14^N and ^15^N NMR data are reported for a series of mesoinoic 1,3,4‐triazoles and some of their salts. The results obtained show that the molecules studied exist in the cyclic mesoionic form with delocalization of the positive charge over the ring atoms. The corresponding
