The theory of magnetic field effects (MFEs) on geminate recombination of highly anisotropic radicals is developed taking into account the anisotropy of reactivity, exchange and electrostatic interactions. Simple analytical expressions for the optically detected MFE amplitude Ps and the CIDEP P, are
A Monte Carlo random flights technique is presented for simulating ion-pair recombination kinetics in systems with ditfitsional and dielectric anisotropy, and is applied to geminate electron-hole recombination in anthracene and naphthalene. While the importance of the anisotropy is evident in the de
Delayedcollection-field measurements of carrier \_eeneration and delayed fluorescence in metal-free phthalocyanine have been shown to exhibit the same time dependence. This indicates the esistence of geminate electron-hole pairs with survival times estending to tens of milliseconds.
