Notes:
1H, 13C, 14N and 15N NMR methods were applied to the study of some Type A mesoionic 1,3-diphenyltetrazoles with various exocyclic groups. The ring structures of these tetrazoles are confirmed by the nitrogen NMR data. The shielding of N-4 increases consecutively by amounts of ca 10 ppm as the bonded exocyclic atom changes from S to C to O.
