✦ Synopsis

In solutions of Michler's kerone in ethanol at 295 K, the fluorescence is almost completely anisotropic. This phenomenon iscaused by the unusually short lifetime of the excited singlet state due to a short intrinsic lifetime and processes leading to a vary low quantum yield. The abso.r$tion, fluorescence and phosphorescence spectra, their degree of anisotropy and the.values of the quantum yield at 295 K, 203 K and 100 K are reported.

Michkr's ketone'sliows phosphorescence from two levelswtich are populated by intersystem crossing from two corrected singbt levels. Th% is indicated by the dependence of phosphoresQace spectra, decay time, and fluorescence-to-phosphorescence intensity ratio on the wavelength of the exciting light.
