Benchmark Calculations with Correlated Molecular Wave Functions. XIII. Potential Energy Curves for He-2, Ne-2, and Ar-2 Using Correlation Consistent Basis Sets Through Augmented Sextuple Zeta.

Abstract

The potential energy curves of the rare gas dimers He2, Ne2, and Ar2 have been computed using correlation consistent basis sets ranging from singly augmented aug-cc-pVDZ sets through triply augmented t-aug-cc-pV6Z sets, with the augmented sextuple basis sets being reported herein. Several methods for including electron correlation were investigated, namely Moller Plesset perturbation theory (MP2, MP3 andMP4) and coupled cluster theory [CCSD and CCSD(T)].
