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.

โฆ Synopsis
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 relative values of the coupling matrix elements for different initial vibronic states.
