B: and A: excited singlet states are directly observed in DPH (all-trans-1,6\_diphenylhexatriene) and DPO (all-trans-1,8diphenyloctatetraene) using picosecond transient absorption spectroscopy. Two absorption bands near 4800 and 6500 A are observed and assigned to B: and A: excited singlet states, r
