✦ Synopsis

Comparison of the "C and "N NMR spectra of 8-azatheophylline with those of its three methylated derivatives and other model compounds from the literature showed that 8-azatheophylline exists to the extent of 80% in the N-2 tautomeric form in DMSO solution.

It is shown that both I3C and ''N NMR measurements provide similar estimates of the position of the prototropic equilibrium exhibited by 2-hydroxy-3-methylindazole in three solvents. The "N NMR study of the pyridine and pyrrole types of nitrogen atoms provided the most quantitatively reliable result

## Abstract ^15^N and ^13^C chemical shifts and the ^1^__J__(^15^N^15^N), ^1^__J__(^15^N^13^C) and ^1^__J__(^13^CH) coupling constants have been determined for a number of ^15^N‐enriched cyclic and acyclic secondary nitramines. The results are interpreted in terms of both electronegativity effects
