✦ Synopsis

The fluorescence of single crystals of p-9,lO-dichioroanthracene at 4.2 K consists solely of excimer emission (T = 95 f 5 ns). The absence of monomenc emission shows that excimer formation in this crystal is not a thermally activated process. This result is confiied by excimer-excimer annihilation studies (~(4.2 K) = 6 X 10mx3 , r(298 Kl = 3 X lo-'* cm3 s-l).
