Application of 119Sn NMR Parameters

Abstract

Publisher Summary This chapter reviews that the impact of 119Sn nuclear magnetic resonance (NMR) parameters, determined either by 119Sn NMR or in the NMR spectra of other nuclei, on tin chemistry is remarkable. Nowadays, tin chemical shifts coupling constants and nuclear spin relaxation, with respect to the physical principles, is growing. At the same time, the application of more or less sophisticated NMR techniques enables one to monitor the reactions, identify the unstable intermediates, discover their relevance for mechanistic implications, assign the structural features, investigate the intra- and intermolecular dynamic processes, or to compare the structures in the solid and liquid state. 119Sn NMR parameters, in addition to those of the more common nuclei, for example, 1H, 13C, or 31P, add to the attempts at a more complete description of the bonding situation. The chapter suggests that it must be emphasized that the great potential of modern NMR spectrometers can be exploited by a multinuclear approach to obtain a large self-consistent set of NMR data. This also includes the isotope induced chemical shifts and long-range coupling constants that have been neglected in the past.
