摘要：

The 1g(1D) ion-pair state of Br2 has been studied by optical-optical double resonance using the 1g(1D)-A3Π(1u)-X1Σg+ photoexcitation scheme. The spectra have been observed in the 0 ≦ v′ ≦ 11 and 2 ≦ J′ ≦ 78 range, and a set of Dunham coefficients calculated from 581 assigned transitions is given as Y00 = 60 288.139(4), Y10 = 154.4778(24), Y20 = -0.39978(46), Y30 = 6.68(26) × 10-4, Y01 = 0.0436549(16), Y11 = -1.5264(13) × 10-4, and Y02 = -1.399(25) × 10-8 (all in cm-1 and σ in parentheses). The Ω-doubling of the 1g(1D) state, q = 1.131(53) × 10-5cm-1, is interpreted to occur through the heterogeneous coupling with the 0g+(1D) state correlating to the same ionic asymptote, Br-(1S) + Br+(1D). © 1992.
