✦ Synopsis

Inclcsion of doubly excited configwations in excited states is investigated in a moment conserving decoupling of the two-partic!c Green's function for molecules with a closed shell ground state. The result obtained is found to correspond to a [2,1] Pad6 approximant decoupling of the Green's function hierarchy. It is shown that this decoupling is equivalent to the equations of motion method of Shibuya, Rose, and McKay.
