A puked dye laser has been used to study the flurxescence of 80 and BO2 in the gas phase at iow pressure. Radbtive Iif+times of 87.2 jt 2.6 and 76.3 f 1.4 ns were obtained for the (000) and (100) Ievels of BOz(A \*I&) and of i3f f 15 and 103 f 6 ns for IeveIs u' = I and 2 of BO(A %I). Unlike BR (A 2

โฆ Synopsis
The excitation spectrum of the double-headed OO'O-00'0 band of B02(AZrIn-X 2~g) wasrecorded by LIF. Special attention was paid to determine the dependence of the radiative lifetime of (OO"O) A 2~ state with J and the quenching by bath gases N2. Ar, 02. The determinations of fluorescence decay were made in real time. The mean radiative lifetime 7, of the A2~3,2(0000) state of l1 BOz was determined to be 91 * 4 ns (1~).
