NMR of transition metals in clusters

The NMR of 195Pt and 59Co on different clusters is used to proof the potentialities of this spectroscopy in the chemistry of transition metals. Platinum NMR, on five platinum atom clusters, leads to complex spectra with second order effect and interesting structural parameters. The resolution of cobalt spectra allows the measurement of all the resonances of clusters on high field spectrometers. The application of Werbelow's theory allows the interpretation of phosphorus 31 spectra. 59Co solid state NMR spectra is also possible and gives all the necessary parameters to interpret the relaxation time measurements of this nucleus in solution.
