In the current implementation of the functional we have included all the double linked terms within (CCSD) approximation. These terms will be important for the accurate description of properties at the stretched geometries. We report the properties for carbon monoxide and hydrogen fluoride molecules, as a function of bond distance and compare our results for carbon monoxide with the full Cl results. We have also reported the properties of methane, tetrafluoromethane, acetylene, difluoroacetylene, water and ammonia. (C) 2013 Elsevier B.V.
