详细
Near-resonant Raman scattering from the electronic excited \({I_2}\left( {0_g^ + \left( {bb} \right)\xrightarrow{{hv}}D0_u^ + \to X0_g^ + } \right)\) state via the intermediate ion-pair D0u+ state to the X one is observed for the first time. The Raman scattering follows a laser pulse. Its intensity IR is inversely proportional to the squared value of detuning from the resonant D, 22, 51 ← 0g+(bb), 7, 52 transition, (Δν2)2, according to the theory of near-resonant Raman scattering. The ratio of Raman D → X scattering intensity to that of the D0u+, νD = 22, JD = 51 → X0g+ luminescence, IR/ID‒X < 1.5 × 10–4 for Δν2 > 0.5 cm–1. The Raman and luminescence spectra are found to be identical.
