β¦ Synopsis
The Wood-Boring-based ab initio model potential method, proposed as a means of including spin-orbit interactions on top of the mass-velocity and Darwin scalar relativistic effects considered by the former Cowan-Griffin-based ab initio model potential method, is applied to the calculation of the (5d, 6s) "~ manifold of atomic platinum, which is recognized to be a difficult task for ab initio methods. The results, which are compared with experiment and with four-comF,ment Dirac-Hartree-Fock plus configuration-interaction calculations, are of the quality required of a relativistic effective core potential method which includes spin-orbit effects.

The geometry corresponding to the minimum potential energy of an O-, H,O cluster is calculated at the second order Moller-Plesset approximation level as a function of the O-O-distanze (path 1) and H-O-distance (path 2). Along path 1 the oxygen atoms are inequivalent for O-O distances larger than 2 A
Ab initio calculations have been performed on model molecular clusters simulating bridging fluorine configurations in fluorinated amorphous silicon. Optimized geometries, total energies and vibrational frequencies have been computed for (SiH&F+ clusters with the terminal SiH, groups eclipsed or stag

Ab initio MO calculations are reported for the C,, -symmetric penetration of C6H6 and C6 H6+' by a helium atom. At the highest level of theory (MP2/6-31G"//MP2/3-21G') barriers of 10.7 and 9.4 eV are obtained. The calculated binding energy of a helium atom to benzene is negligible. These computation
