Analysis of High-Resolution NMR Spectra

Abstract

Van Vleck has shown the usefulness of moment calculations in the interpretation of magnetic interactions found in crystals. This approach has been extended to include liquids where separate resonances may be well resolved. In a simple chemical system containing only two groups of nuclei, this procedure allows the direct calculation of the spin coupling constant and the chemical shift in terms of directly measured quantities; in more complex systems, it allows some information to be obtained without finding the complete solution to a particular problem.
