β¦ Synopsis
A ne% ion-pair state of Br2. designated as F(O:), has been identiiied. The excitation to this state was performed by a sequential three-photon transition through the B 3110 ; state. The molecular parameters %ere derived to be Te = 53900.5(S), we = 154.8(S), uexe = 0.76(20), and Be = 0.03970(17) cm -I + Br+(3Po)_ for the F(O:) ion-pair state, which correlates to Br-('S)
