摘要：
Near-resonant Raman scattering from the electronic excited state via the intermediate ion-pair D0 (u) (+) state to the X one is observed for the first time. The Raman scattering follows a laser pulse. Its intensity I (R) is inversely proportional to the squared value of detuning from the resonant D, 22, 51 a dagger 0 (g) (+)(bb), 7, 52 transition, (Delta nu(2))(2), according to the theory of near-resonant Raman scattering. The ratio of Raman D -> X scattering intensity to that of the D0 (u) (+), nu (D) = 22, J (D) = 51 -> X0 (g) (+) luminescence, I (R) /I (DaEuro'X) < 1.5 x 10(-4) for Delta nu(2) > 0.5 cm(-1). The Raman and luminescence spectra are found to be identical.
