Fluorcscencc spectra are presented, originstins from upper excited singlet stntcs in three santhene dyes. The cxpcrimentnl method, using biphoknic pulsed laser escitation, is shown to have advantages over sir&-photon ultraviolet irradiation. It is further shown that the observed spectra dcpcnd on th
