Abstract
Results of MCSCF(GVB)+CI calculations are presented for the H3C-AlH an d H3CAl-H bond dissociation energies. Using the AIH, molecule as a tes t case it is shown that reliable bond energies can be obtained by cons idering only the differential correlation effects on the chemical bond being broken and the relaxation effects on its neighbouring bonds. Th e Al-H bond (39.32 kcal mol-1) is found to be stronger than the Al-C b ond (33.36 kcal mol-1), but both bonds are weaker than the HAl-H bond.
