N2 - Near-resonant Raman scattering from the electronic excited I2(0g+(bb)→hvD0u+→X0g+) 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.
