title: Communications: Accurate and efficient approximations to explicitly correlated coupled-cluster singles and doubles, CCSD-F12.
abstract: We propose a novel explicitly correlated coupled-cluster singles and doubles method CCSD(F12(*)), which retains the accuracy of CCSD-F12 while the computational costs are only insignificantly larger than those for a conventional CCSD calculation.
