Molecular Structure Determination by Nmr Spectroscopy

Abstract

The spin Hamiltonian giving rise to the energy levels of a system of nuclei in a partially oriented molecule is described. The splittings in the n.m.r. spectra are mainly due to the direct dipolar interactions of the nuclei, and their measurement is therefore capable of giving relative distances between magnetic nuclei. The limitations to the utility of this method of structure determination are considered, including the various effects of non-rigidity, anisotropy in the indirect spin-coupling tensor and the complexity of the spectra. An application to the determination of metal-hydrogen distances in transition-metal hydrides is described. © 1974, Walter de Gruyter. © 1974, Walter de Gruyter. All rights reserved.
