Nitrogen n.m.r. spectroscopy

Abstract

Various aspects of nitrogen n.m.r. spectroscopy and its applications to the structural investigations of molecules are discussed. A brief survey of direct and indirect measurements of 14 N and 15 N n.m.r. spectra is given. Nitrogen chemical shifts and nitrogcn coupling constants are presented as a means of differentiation between isomeric or tautomeric structures, structural assignments, and investigation of intermolecular effects in liquids. Potential applications of 14 N quadrupolar relaxation data in the study of molecular rotations and electron charge distribution are briefly considered.
