Abstract
Adiabatic correlation rules for linear and nonlinear polyatomic molecules suitable for a discussion of elementary reactions involving polyatomic reactions complexes are formulated. These correlation rules permit the determination of the electronic and vibronic species of the reaction surfaces and of the term manifold of the resulting molecules from the states of the separated components without detailed reference to their electronic configurations. This formulation is based upon group theoretical arguments and utilizes a structural specification of the intermediate reaction complex from which one can obtain, via auxiliary linear intermediate complexes, the desired correlations by means of species resolution tables for linear to nonlinear point groups. The determination of the electronic (and vibronic) species of the intermediate complex and the products permits a detailed investigation of the optical transitions, predissociations and perturbations between the various energy levels. The correlation rules presented here should be regarded as a first attemt to extend the Wigner-Witmer type rules to simple nonlinear triatomic and tetratomic molecules in a manner most suited for the discussion of elementary reactions involving electronically excited states.
