WebJun 29, 2016 · It is generally recommended not to use a correlation consistent (cc) basis set with a DFT method (and I guess conversely, a basis set aimed at DFT should not be used with a coupled cluster method). Why then would people benchmark methods using seemingly inappropriate basis sets. E.g. a cc basis set with an M06 functional. http://users.df.uba.ar/dmitnik/estructura3/bases/biblio/SFSU-ElectronicStructure-Lect-3.pdf
