The homolytic bond dissociation energies of the transition-metal neutral hydrides, D’(M-H) (M = V, Cr) , are experimentally determined by using guided ion beam tandem mass spectrometry to measure the kinetic energy dependence of the endothermic hydride abstraction reactions of M+ with mono-, di-, and trimethylamine. From the thresholds of these reactions, we derive the 0 K values of DO(V-H)=2.1...
