摘要：

The effect of anisotropic diffusion upon the geminate survival probability of a pair of neutral particles is discussed. A concise, if simple, expression for the bulk recombination rate coefficient is derived using an integral relationship between it and the geminate survival probability. The resultant equation is similar to that for isotropic media, but differs in detail. The bimolecular annihilation of triplet excitons in anthracene crystals is modelled using the present treatment and the predicted reaction ellipsoid suggests a diffusive picture for excitonic motion. © 1990.
