Abstract
H-1, C-13, N-14 and N-15 NMR results are reported for some mesoionic 1 ,2,3-triazoles and related compounds. It is demonstrated that N-14 NMR linewidths are dependent on the charge present on the nitrogen atom. In addition, it is shown that nitrogen NMR is of great value in the de termination of the site of protonation, the ability to distinguish rea dily between mesoionic cyclic and non-cyclic structures and to follow the transformation between such structures.
