Bond dissociation energies at 0 K (D0) and electronic bond dissociation energies (ZPE exclusive) (De) for the methyl complexes (kcal∕mol) from experiment and the errors (theory-experiment) obtained by other authors and obtained with B3LYP for our different basis sets. Experimental values for D0 taken from Refs. 49, 53, 54, 55 and quoted in Ref. 57. L2 is the LAN2DZ basis set.
