We report mcasuriincnts on spin-lattjce relaxation (SLR) of linear triplet excitons in I,4 dibromonaphthalcne .', (1.4 D?N) sin& crystals at liquid ~~,eliktemperatures and at room temperature. SLR was found to be temperature dcptidcnt but isotropkrvith respect 'to the T;;ternal magnetic field.
Proton spin-lattice relaxation rate constants have been measured as a function of magnetic field strength for water, water-glycerol solution, cyclohexane, methanol, benzene, acetone, acetonitrile, and dimethyl sulfoxide. The magnetic relaxation dispersion is well approximated by a Lorentzian shape.
