## Abstract The motion of excitons is considered by a stochastic model comprising both its coherent and incoherent motion. The coherent motion is determined by the exchange interaction integral __J__ whereas the incoherent motion is described by the strengths of local (Ξ³~0~) and nonβlocal (Ξ³~1~) fl
The inlcraction of triplet excitons and protons in molecular crystals gives rise to n longitudinal relsxation time TI ex of the protens. We calculate the dependence of Tt ex on the external magnetic field, on the dimensionality and on the kind of the exciton motion. Beyond this the optical nuclear s
