Ab initio multiconfiguration self-consistent field (MCSCF) and configuration interaction (CI) calculations have yielded an activation energy of 80.9 +- 3.0 kcal/mol for the dissociation of formaldehyde to H/sub 2/ and CO on the ground state potential energy surface. The error limits are estimates based on an analysis of the effects of one-particle basis set, electron correlation, and transition state structure on the activation energy. Accurate structures and harmonic frequencies are presented for H/sub 2/CO (X /sup 1/A/sub 1/) and the transition state.
