A number of modern multiple pulse NMR techniques have been applied to tritium for the first time, demonstrating the power of this approach for analysis of complex isotopic mixtures. In particular, double quantum filtering, DEPT, and tritium homodecoupled BB-proton-decoupled one-dimensional spectra have been obtained. In addition, phase sensitive tritium COSY, tritium-proton correlation, and tritium J-resolved two-dimensional experiments are reported. These experiments yield a great deal of information about the isotopic distribution in the subject molecule-n-propylbenzene-produced by the catalytic tritiation of {beta}-methylstyrene. Analysis of these NMR data has allowed us to reach some mechanistic conclusions about hydrogenation reactions. 25 refs., 5 figs., 2 tabs.
