## Abstract Solid‐state cross‐polarization magic angle spinning ^13^C, ^77^Se and ^15^N NMR spectra were recorded for 1,3‐imidazolidine‐2‐selenone, its N‐substituted derivatives and some related compounds. The spinning sideband manifold intensities were used to obtain principal values of ^13^C and
## Abstract ^1^H, ^13^C, ^14^N and ^15^N 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 __
