摘要:
The reduced multireference coupled cluster method with singles and doubles (RMR CCSD) is extended to handle high spin open-shell systems within the framework of the unitary group based coupled cluster theory (UGA CCSD). The method is applied to several states of multiply bonded diatomics, namely to the X2
