✦ Synopsis

A trnnsicnt absorption is observed in nnthraccne (A/-N, N-diethyianiline (D) sofutions in toiuene excited by the 3371k line of n nitrogen laser. The lifetime of the transient matches that of the fluorescence of the excited (DA) charge transfer complex. The absorption is assigned to a transition from the fluorescent CT state to a higher CT singlet of the complex. Excited singlet-singlet absorptions nre also observed fox the free anthracene and Zi, N-diethylani~jne molecules.
