Abstract:
A new ion-pair state of Br2 has been observed by an optical–optical double resonance technique utilizing ultraviolet fluorescence detection. The OODR excitations proceed in an one-photon resonant three-photon absorption through the B3Π (0+u) state. The effects of polarization on their transition strengths are used to determine the symmetry of excited molecular state formed by two-photon absorption from the B state. The results indicate that the new state has the 0+u symmetry with Te=53 899.6(7) cm−1, ωe=155.8(2) cm−1, and re=3.276(8) Å for 79Br2. This state is expected to correlate with Br+(3P0)+Br−(1S) and named F (0+u) after the well-defined I2 molecule. The single rovibronic fluorescence spectra of the F(0+u) state show several transitions terminating on low-lying valence states.
