The non-diagonal matrix elements in the adiabatic Born-Oppenheimer approximation are considered. The effect of the Q-dependence of the electronic energy denominator is calculated explicitly for an arbitrary initial and final state. It is shown that the inclusion of this effect does not change the re

β¦ Synopsis
The lierzberg-Teller expansion over floating-orbital zero-order w&vefunctions is used to derive vibronic coupling iMegals. These arc shown to be eastly obtained by the use of standard semi-empirical hf0 methods.

A general expression is dcrivcd that relates the matrix elements of position and momenttim allolving for the possibility of a mixed basis. It is shown that when Born-Oppenhcimcr wavefunctions for IWO different clcctronic states arc used as basis functions, the use of the usual expression relating ma
In the present article, we outline a simple scheme for generating configuration interaction matrix elements for spinαorbit interactions in molecules. The procedure leads to a close parallelism with spin-free permutation-group approaches. Unitary shift operators were successfully used on the orbital
The implementation of a recently proposed technique for evaluating matrix elements of the form <~I,j(r; R)I 0~I,l(r; R)/ ORa} r using analytic gradient techniques is described. The ~VK(r; R) are developed from state-averaged multiconfiguration self-consistent-field/configuration interaction (CI) wav
