We present an accurate calculation of the intermolecular potential surface for the van der Waals complex He-H20 using complete fourth-order M¢ller-Plesset perturbation theory (MP4) with an efficient basis set containing bond functions. The calculation gives a global minimum at R = 3.15 /~, 0 = 105 °

✦ Synopsis
Potential enera surfaces for the grotmd and excited state interactions of Hz with H$ have been c&x&ted using SCF and CI techniques. Six geometries have been studied, in which the Hz and G bond lengths were restricted to their eqtii mm values, and t3e intermolecular Hz-G distance was varied from 05 to 20 au. Ground state binding energies range from 0.4 to 1.6 eV. The most stable geometry was found to be a perpendicular orientation with the I$ molecule lying on a line bisecting the Hz bond axis.
