Using helicity-amplitude techniques, we derive the partonic level spin-spin asymmetries {ital {cflx a}}{sub {ital L}{ital L}} for all of the processes relevant to the hadronic production of three-jet and two-jet plus photon final states. We discuss the structure of the observable asymmetries in these processes in polarized proton-proton collisions and their dependence on the spin-dependent parton distributions.
