Distributive and Actuarial Elements CI energy derivatives. Non-adiabatic coupling matrix elements can be extracted from this framework by using a common orbital set to describe both states. CI non-adiabatic coupling matrix elements are simply obtained by employing transition density matrices in the multi-reference CI gradient program.

Life Cycle, Life Course, Lifespanssion, which includes electron correlation, which can be analytically differentiated. This implementation requires the evaluation of all first order orbital changes U., but eliminates the evaluation of U.. Four index transformations of derivative integrals are required. An application of the method to formaldehyde (42 basis functions) is reported.

Approaches to Ethics and Justices. We discuss some of the details of the algorithm including how to optimally use it to obtain a first-order estimate of the MCSCF wave function at a new point. We apply the algorithm to the problems of the rotation barrier and dissociation in H.O. (minimum basis set) and the dissociation in NH. (double zeta plus polarization basis).
