Bond Dissociation Energies Yu-Ran Luo 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) = ∆fHo(R) + ∆fHo(X) – ∆fHo(RX). The enthalpy of formation ∆fHo of a large number of atoms, free radicals, ions, clusters and compounds is available from the websites of NIST, NASA, CODATA, and IUPAC. Most authors prefer to use the BDE values at 298.15 K. The following seven tables provide essential information of experimental BDE values of R−X and R+−X bonds.
(1) Table 1: Bond Dissociation Energies in Diatomic Molecules (2) Table 2: Enthalpy of Formation of Gaseous Atoms (3) Table 3: Bond Dissociation Energies in Polyatomic Molecules (4) Table 4: Enthalpies of Formation of Free Radicals and Other Transient Species (5) Table 5: Bond Dissociation Energies of Common Organic Molecules (6) Table 6: Bond Dissociation Energies in Diatomic Cations (7) Table 7: Bond Dissociation Energies in Polyatomic Cations The data in these tables have been revised through September 2009.
TABLE 1. Bond Dissociation Energies in Diatomic Molecules The BDEs in diatomic species have usually been measured by spectroscopy or mass spectrometry. In the absence of data on the enthalpy function, the values at 0 K, Do(A−B), are converted to Do298 by the approximate equation: Do298(A−B) ≈ Do(A−B) + (3/2)RT = Do(A−B) + 3.7181 kJ mol–1
