In the present paper we extend earlier work on spin-dominated transitions using a plane wave formalism to a full distorted wave treatment. We perform a distorted wave calculation using a relativistic approach to nucleon-nucleus inelastic scattering. We focus on the $1^{+}$, T=0 transition in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ using 500 MeV protons with special emphasis on spin observables. We obtain sizable effects for spin observable differences without invoking exchange processes.
