Popis:	An optical and magnetic resonance study on neat 1,4‐dibromobenzene crystals shows that the molecules in their lowest triplet state are distorted into a chair‐like shape and confirms previous conclusions about the one‐dimensional character of the triplet excitons. From a study of the phosphorescence spectrum at various temperatures it is found that the band width of the triplet excitons is (−1.0±0.15) cm−1 and that the k=0 state is at the bottom of the band.
