The bond dissociation energy defined as the energy gain in adding a Hz molecule to a Vt (Hz)n cluster exhibits an anomalous pattern. Instead of decreasing as a function of n, as is the case in Co+ (II,), clusters, it increases as the number of H2 Iigands increases from 5 to 6. To understand the orig

✦ Synopsis
In a recent study, we reported experimental determinations of bond dissociation energies and entropies for V+(H2)n (n = 1 to 6) and suggested that a spin change from quintet to triplet occurs upon addition of the sixth H 2 ligand. A very recent theoretical paper by Niu et al. disputes this and concludes that the experimental results are consistent with purely quintet clusters (J.

## Abstract Six density function theory methods (B3LYP, B3P86, MPWB1K1, MPWPW91, PBEPBE, TPSS1KCIS3) were used to calculate bond dissociation enthalpies of nitro compounds, where the B3P86 method was found to give the most accurate predictions. Using the B3P86 method __meta__‐ and __para__‐substitu

We report a rapid increase in the propensity of D,O molecules to incorporate into (H,O); clusters upon collisions between D,O and a distribution of (H\*O);, 6< n c 25, clusters. We interpret this effect by invoking a size-dependent associative electron detachment cross section which increases rapidl
