| Abstract: | We have measured the spin—lattice relaxation rates of the linear chain triplet excitons in 1,2,4,5-tetrachlorobenzene single crystals as a function of the direction of the magnetic field by means of laser flash excitation and electron spin-echo techniques. The observed orientational dependence is explained by interchain hopping between the two magnetically inequivalent exciton chains. |
