NMR OF TRANSITION-METALS IN CLUSTERS

The NMR of Pt-195 and Co-95 on different clusters is used to proof the potentialities of this spectroscopy in the chemistry of transition me tals. Platinum NMR, on five platinum atom clusters, leads to complex s pectra with second order effect and interesting structural parameters. The resolution of cobalt spectra allows the measurement of all the re sonances of clusters on high field spectrometers. The application of W erbelow's theory allows the interpretation of phosphorus 31 spectra. C o-59 solid state NMR spectra is also possible and gives all the necess ary parameters to interpret the relaxation time measurements of this n ucleus in solution.
