Analyzing the Local Basis Set Superposition Error -- a case study of CO adsorption on rutile(110)

Abstract

The aim of this letter is to introduce a new method to analyze the local basis set superposition error (LBSSE) using local counterpoise corrections (CP) in order to converge a basis set for a given compound. Using this approach, we are able to define a basis set composition for a CO molecule adsorbed on rutile(110), which can be regarded as complete. In addition to a new LBSSE analysis, adsorption energies of CO on rutile(110) at the MP2 and CCSD level of theory are presented.
