## I l Introduction In pseudo-potential theory [1,2], the valence electrons only are explicitely treated quantum mechanically; the influence of the core electrons is simulated by a nonlocal pseudo-potential. The following molecular electronic pseudo-hamiltonian is then used:

β¦ Synopsis
The use of atomic pseudo-potentials in ckcutaiions of atomic inmractions is briefly discussed. It is shove that an appropriate choice of pseudo-po~n~ial leads to the appearance of the van der W&s interactions in first order. Care is needed in the choice otentiat lest spurious long-range forces appear. Explicit calculations are and comparison made with the results of conventional caiculntions.
accuracy is obtained over a wide range of internuclear separations.

Harmonic lattice dynamics is used to calculate the sound velocities in crystalline 7,7,8,8-tetracyanoquinodimethane at T = 0 K and zero pressure.
