Abstract
We propose a simple model for reaction-diffusion systems with orientational constraints on the reactivity of particles, and map it onto a field theory with upper critical dimension To the two-loop level, long-time particle density is given by the same universal expression as for a nonsteric system, with for For slow rotations of the particles we find an intermediate regime where with the crossover to the nonsteric asymptotics determined by the rates of rotations and reactions. Consequences for experiments are discussed.
