✦ Synopsis

An explicit comparison is made between first-and second-order perturbation expressions for exchange interactions given by the Eisenschitz-London-Van

der Avoird formalism and by a Schrocdinger-type procedure. Relative three-atom exchange interactions are found to be very similar in the two formalisms.
