We use a theorem of S. Tolman and J. Weitsman (The cohomology rings of Abelian symplectic quotients, math. DGΓ‚9807173) to find explicit formul$ for the rational cohomology rings of the symplectic reduction of flag varieties in C n , or generic coadjoint orbits of SU(n), by (maximal) torus actions. W
