Overview of ⁹⁵Mo NMR

Abstract

Nuclear magnetic resonance is a powerful technique for studying the structure and dynamics of molecules in solution. Nuclear magnetic resonance experiments using ¹⁵N and ¹H nuclei are discussed elsewhere in this volume and another potentially useful nucleus for NMR studies relative to nitrogen fixation is ⁹⁵Mo. .The nuclear properties of ⁹⁵Mo are listed in Table 1. The relatively low frequency for ⁹⁵Mo, the quadrupole moment of the nucleus and the low sensitivity relative to many other common nuclei have limited the NMR investigations of this nucleus in chemical systems. An extensive review¹ of heteronuclear NMR published in 1978 required only one page to tabulate and discuss all of the known NMR data for ^95,97Mo. However, the recent advent of commercially available multinuclear NMR spectrometers with super-conducting magnets and moderately high fields promises to make ⁹⁵Mo NMR spectroscopy more accessible. Herein, an overview of the chemical applications of ⁹⁵Mo NMR is presented.
