Structures, relative energies, and ligand dissociation energies of iridium carbonyl phosphine clusters

Bond dissociation energies

The bond dissociation energy (enthalpy) is also referred to as bond disruption energy, bond energy, bond strength, or binding energy (abbreviation: BDE, BE, or D) . It is defined as the standard enthalpy change of the following fission: R−X → R + X . The BDE, denoted by Do(R−X), is usually derived by the thermochemical equation, Do(R−X) = ∆fH o(R) + ∆fH o(X) – ∆fH o(RX) . The enthalpy of format...

Ionization energies and structures of lithium doped silicon clusters.

We report on a combined experimental and theoretical study of the ionization energies and structures of small lithium doped silicon clusters, SinLim with n = 5-11 and m = 3-6. Photoionization efficiency curves are measured in the 4.68-6.24 eV range and subsequently compared with calculated values of both vertical and adiabatic ionization energies for the lowest energy isomers obtained using den...

Ferrocenyl Phosphine Substitution on Triruthenium Carbonyl Clusters

Bond dissociation energies of organic molecules.

In this Account we have compiled a list of reliable bond energies that are based on a set of critically evaluated experiments. A brief description of the three most important experimental techniques for measuring bond energies is provided. We demonstrate how these experimental data can be applied to yield the heats of formation of organic radicals and the bond enthalpies of more than 100 repres...
