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 benz
The fluorescence emission from the S2 state of xanthione in benzene solution was time resolved using a Nd3' glass mode-locked laser driven light gate technique. Using a separate optical apparatus, in conjunction with the mode-locked laser, transient absorption spectta were recorded at times subseque
