  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.
