Description

A considerable difference of iodine emission spectra after optical-optical double resonance excitation of the E0+g, vE = 19, JE ∼ 55 and JE ∼ 85 rovibronic levels is observed. The latter include strong transitions from the γ1u ion-pair state to valence ones. This feature is interpreted as a result of hyperfine coupling of near-resonant E0+g, vE = 19, JE = 81 and γ1u, vγ = 18, Jγ = 80 states. The hyperfine matrix element and dipole moment functions of transitions from the γ state are estimated. The hyperfine g/u mixing of the iodine ion-pair states is observed for the first time
