Abstract:
This thesis examines the application of 15N and 95Mo Nuclear Magnetic Resonance Spectroscopy in studies relevant to nitrogen fixation and describes further development of technique. Chapter 1 provides a general introduction to the study of nitrogen fixation but with reference to some specific examples of areas of interest. Chapter 2 is in two sections, the first dealing with the practical aspect of NMR spectroscopy and particularly 15N and 95Mo. The problems involved with the study of N and Mo. The second section gives a general introduction to nuclear magnetic shielding theory and shows some of the ways in which this has been applied. Chapter 3 describes the effect of change in co-ligands on the physical properties of some nitrosyl and diazenidocomplexes. Chapter 4 discusses a possible spectrochemical series 95Mo of ligands based on the Mo NMR parameters of complexes. Chapter 5 deals with the use of 15N NMR spectroscopy to probe the structure of nitrogenous ligands which show some form of structural isomerism. Chapter 6 is a compilation of data obtained by NMR spectroscopy on protonation reactions involving dinitrogen and hydrazido(2-)-complexes, with some possible interpretations. Chapter 7 mentions initial enzyme studies by 95Mo NMR spectroscopy and concludes with some general comments and suggestions for the direction of future work.
