✦ Synopsis

chuge-transfer phosphorescence and fluoresccnLe were observed for a blphenyl sqlc crystal contamm:: 1,2,4,S-letracyanobenzenc as a guest at various temperatures between 29 and I 47Β°K The non+.ponenttat phosphorescence decay due to the spm ahgnment m the charge-transfcr_trlplet state was first observed and the phosphorescence hfctlmcs of the three sublevels were determmed to be 0 9, 2 5, and 7 9 set at 1 47Β°K
