✦ Synopsis
Sl+
SO internal conversion (Jqd and S1 -+ T1 (JqSC) intersystem crossing rate constants were determined and compared in the group of mono-and di-aza derivatives of 1 ,Zbcnzanthracene.
Quantum y~clds of triplet formation (Uqsc) were obtained from puked photoacoustic measurements. The extremely fast k1SC = 4 X 10" s-l was found for 1 ,a-benzphenazinc in aprotic solvents. kIc of free bases and monoprotonated spenes are two orders of magnitude greater than that of the parent hydrocarbon.
