Ab initio multireference configuration interaction calculations were performed on both barrierless PESs (where the minimum energy path involves the insertion of the O atom into the middle of the H2(+) bond), and suitable analytical expressions were developed for the first time and used in quasiclassical trajectory (QCT) calculations. k(1) ≈ ...

The equilibrium distance Equilibrium distances, Rm (in Å) and energies, e (in kcal mol 1) of the isotropic term and energy of the H2O-N2 system has been compared with those for the H2O-H2, H2O-N2, H2O-O2, H2O-rare-gas-atom systems, as determined in this obtained from a molecular beam scattering experimental work work at the CCSD(T ...

The distance between Ni and C2 decreases from 2.51 to 1.99 Å, whilst the C2-H2 bond elongates from 1.14 to 2.35 Å; this isomerisation suggests that the partial cleavage of the C2-H2 bond leads to the formation of a C-H insertion product; indeed, the hydrogen atom of the C 6 H 6 D 6 molecule is removed from the carbon atom, and it is ...
