✦ Synopsis

The ESR spectrum of linear triplet e&tons in single crystals of 1 $dibromonaphthaIene (DBN) was studied ig the temperature range berween 2°K and room temperature. The exciton migration maintains its one-dimensional character up to 300°K. The ESR hnewidth is strongly temperature dependent. This fact results from a transition . from coherent to incoherent exciton motion around 16°K
