Part of the Developments in Applied Spectroscopy book series (DAIS, volume 8)


Quadrupole splitting in tin Mössbauer spectra can arise from the interaction between the nuclear quadrupole moment of the 119mSn nucleus and a non-spherically symmetric electric field produced by extra-nuclear charges. Such a situation is produced by the placement of charges of different magnitudes at internuclear distances in tetrahedral or octahedral arrays, or by equal charges placed in arrays of lower symmetries. A simple model using point charges to represent attached atoms is used to calculate the relative magnitudes of the splittings expected for various substitutional patterns involving various coordination numbers and simple symmetries found in known tin systems. The results of these calculations are tested with respect to quadrupole splitting data obtained for organotin (IV) compounds and complexes, and the appropriateness of the point-charge model for these systems is discussed.
