The spin‐shift formalism is used to define propagators which describe transitions from a spin‐adapted reference state to final states with a known fixed spin. A brief discussion of the algebraic superoperator approach is made, and a theorem is presented which allows the generation of operator basis sets in a manner analogous to the standard closed‐shell formalism.
