For triplet excitons in non‐resonant pairs of differently oriented molecules the saturation of the ESR lineshape is investigated. The model takes into account the coherent exciton motion, an inhomogeneous distribution of electronic excitation energies, Zeeman and fine‐structure terms, and the microscopic interaction with phonons.
