摘要：

Proton longitudinal and transverse relaxation rates of hybrido resonances of different isotopomers in (H{sub 3}Pt{sub 2}(Dpe){sub 2})(BF{sub 4}) (Dpe = bis(diphenylphosphino)ethane) show significant differences in the satellite peaks with respect to the central ones that can be used to evaluate the activation energy of the intramolecular exchange process and the chemical shift separation between bridging and terminal sites. An alternative route to get an estimation of the chemical shift values of the bridging and terminal hydrides in this derivative has been pursued by considering the isotopic shift of the three H{sub 3}, H{sub 2}D, and HD{sub 2} isotopomers at different temperatures. 9 refs., 2 figs.
