Abstract
Using high-resolution Fourier transform emission techniques, we have resolved rotational structure in the D0u+(3P2) → X0g+ emission following collisional transfer from the E0g+(3P2) state in I2. The P:R branch ratios in the E0g+(3P2) → D0u+(3P2) transfer are found to vary enormously with vE and vD. We show that the observed intensities are all consistent with the transfer being dominated by long-range, near-resonant collisions with residual H2O. Unequal P:R branch ratios in the E0g+(3P2) → A1u emission have been shown to result from mixing of the E0g+(3P2) and β1g(3P2) states via Ω-uncoupling.
