Overview of 95Mo NMR

  • John H. Enemark


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.
