✦ Synopsis

We preses the SI -1 So fluorescente spectrum, between 740 and 940 om, of azulene sohitions (íOm3 M ìn methanol) excited wïth a @svitched ruby laser. The nitrogerrlaser excïted Sz + SI fíuorescence spectrum, between 700 and 930 om, is also reporteb Tbe transient St + Sn s@etrmn between 500 and 6.50 run was studïed, using synchmnous nitrogen laser and dye Iaser e?rätatïon The Ss C'B~(3)) state of arulene was found to be Iocated at 45.500 cm-' and the cross section 025 of the transïent absorption & +Ss is estimakd to be 3 x lO_" cm2/mo!ecuk.
