The ESR spectrum of linear triplet e&tons in single crystals of 1 $dibromonaphthaIene (DBN) was studied ig the temperature range berween 2Β°K and room temperature. The exciton migration maintains its one-dimensional character up to 300Β°K. The ESR hnewidth is strongly temperature dependent. This fact
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.
