Abstract
A multiconfiguration version of the time-dependent Hartree approximation has been applied to various molecular systems, including direct photodissociation, vibrational predissociation and photodissociation on a solid surface. It is shown that the omission of dynamic correlations by the simple time-dependent Hartree approximation can be corrected by the multiconfiguration formalism and the results converge to the exact solution. Because of a different scaling law with the dimensionality of the problem, this method may find applications in large dimensional systems which are not accessible by conventional exact methods.
