Wood, Damian Moran, and Leo Radom*: Bond Dissociation Energies and Radical Stabilization Energies: An Assessment of Contemporary Theoretical Procedures Page 13638. As a consequence of using an incorrect value for the B3-LYP/6-31G(d) C-H bond length in methane, the bond dissociation energies (BDEs) for methane, and hence all the radical stabilization energies (RSEs), obtained with density functional theory (DFT) procedures and listed respectively in Tables 1 (page 13640) and 2 (page 13642), are incorrect. However, none of our qualitative conclusions are affected. The corrected BDEs for methane are presented in Table 1, and the corrected RSEs are compared with W1 and experimental values in Table 2.
