Abstract: A semiempirical quantum-chemical MINDO/2 method has been tested for description of the dissociation curves of the CH bond in formaldehyde in its ground and excited singlet and triplet states. A Fock operator of Nesbeťs type was used in the SCF procedure; the consequent configuration interaction contained monoexcited and some selected biexcited configurations necessary for correct description of the dissociation. Irrespective of some shortcomings of MINDO/2 parametrization for describing excited states it seems to be suitable for qualitative conclusions on the mechanism of photolytic decomposition of organic ketones.
