Transition metal hydrides MH<sup>+/0/−</sup> (M = Sc−Zn): Benchmark study and periodic trends
2018, Computational and Theoretical ChemistryCitation Excerpt :In the past studies, we obtained some data, such as the bond energies (theoretical and experimental values), bond lengths and spectral properties of a large number of [M–H]+, as well as the excitation energy of TMHs [17–20]. Armentrout proved that the first and second rows of periodic trends of TMH are linear regression [21]. It provides a very valuable theoretical basis for this research.
Gas-phase ion chemistry of rare earths and actinides
2014, Handbook on the Physics and Chemistry of Rare EarthsCitation Excerpt :Sc, Y, La, and Lu are the rare earths that have been examined by Armentrout and coworkers, and Table 8 presents a selection of bond dissociation energies of the monopositive cations. Periodic trends in the bond energies for the transition metals were uncovered and assessed in terms of the atomic electronic configurations and PEs, and this was an early seminal contribution of Armentrout and Beauchamp (Armentrout, 1990, 2003; Armentrout and Beauchamp, 1989; Armentrout and Clemmer, 1992; Armentrout and Georgiadis, 1988; Armentrout and Kickel, 1996; Armentrout et al., 1981, 1989; Kretzschmar et al., 2001). Some of these trends/correlations are illustrated by the examples presented in Figs. 22 and 23: in the former, the first-row (including Sc+) and the second-row (including Y+) transition metal ion hydride bond energies are plotted as a function of the atomic metal ion PE to an s1dn spin-decoupled state; in the latter, the bond energies of Sc+ to isoelectronic series of ligands, CH3, NH2, and OH or CH2, NH, and O, are plotted as a function of the number of electron lone pairs on the ligands or the presumed bond order.

2000, International Journal of Mass SpectrometryCitation Excerpt :Nevertheless, the data in the methane systems leaves no doubt that the Nb+–CH2 BDE cannot be this low. There are no barriers to these reactions in excess of the endothermicity (which would raise the BDE anyway), as demonstrated by the efficiency of the reverse process [14,34]. The good agreement with the value obtained in the propane system where formation of NbCH2+ occurs by a different mechanism indicates that there are no obvious systematic effects in the determination of this BDE.
