The excitonic T, triplet states in single crystals of 2,3dimethylnaphthalene (DMN) and 2,3\_dimethylanthracene (DMA) exhibit broadened ( 120 and 1 IO cm-', respectively) asymmetric absorption lines at helium temperature. The corresponding phosphorescence lines are narrower (40 and 50 cm-'), red-shif
## Abstract A theoretical expression is derived for a cubic crystal lattice disordered by the introduction of a vacancy‐interstitial pair. Considering only the nearest neighbour interaction for the interstitial atom, the double‐time Green's function has been formally calculated and the ratio of the
