✦ Synopsis

drrr tizssberg. 3400 Corringen. Federal Republic of Germany A d&> cd lluorc,cence S2 -So from the second exited singlet state (Sz) of4.6,8-trimethylazulene (TMA), resulting lrum tlolrlo-triplet-triplcr annihilation Tt + Tt --S2 + So, has been observed. No delayed fluorescence from an upper es-r~mcr stati' ofTMA W.IS found. The extrapolated low-temperature triplet hfetime of TMA is 5140 ps.
