✦ Synopsis

The blue and red fluorcscencc of cryptocyanine colutions Wits observed under conditions of steady-stay light evcltation and during Q-swttched ruby her cxitation.

Experimental results give evidence that tilt blue fiuore~fcncc IS Sz -* So transition.

An anomalous fluorescence with a quantum yield of 0.017 near BOO0 cm-' is detected from he?rane solutions of aceanthrylene. Excitation and synchronous scan spectra verify that the second acited state with a lifetime of 43 ns is the source of the fluorescence. The absorption spectrum is simulated by
