irradiation of benzophcnone in isopropanol solution results in orange fluorescence, the yield of which depends on the laser pulse duration. This is shown to be due to benzophenone ketyl (hydroxydiphenyl methyl), formed as a photoproduct. It is shown that simple time-resolved fluorescence measurement
