✦ Synopsis
Calculations of barriers and conformations using the SCF XCY SW method are discussed. Results of calculations of the inve+m barrier in ammonia and the barrier to internal ratation oi hydrogen peroxide using different sets of sphere radii are also prescnteci and discussed. These barriers arc heavily dependent on the choice of sphere radii, but this dependence is due to the way the totat energy is computed in the exjsting progiams.

The ab initio unrestricted Hartree-Fock (UHF) method with inclusion of a SCF Madelung potential has been applied to the YBa#Zu,O, cluster. Mulliken's population analysis and Edwald's lattice summation technique are used for the evaluation of the Madelung potential. Approximately equivalent charge di
