✦ Synopsis

The lluorescencc fiferimes and quantum yields of the S2 state of xantbionc in benzene and isoloctanc sotution at room temperature have been mcnsurcd.

The Sz iifctimn wcrc found to bc I8 2 2 ps in bcnzcnc and 43 % 'I! ps in iso-ocrane. The non-radiative decay rate constant is 5.6 x lO'* s-l in benzene and 2.3 X IO** s-t in iso-octane.
