Femtosecond fluorescence upconversion experiments as performed for photoexcited auramine (a diphenylaminemethane dye) in liquid solution are discussed. Upon pulsed laser excitation the solute shows a dynamic Stokes shift as well as a drop in fluorescence intensity in only a few picoseconds. From a s
