N2 - Optical-optical double resonance spectroscopy is used to obtain total rate constants, electronic branching ratios, and vibrational product state distributions for non-adiabatic transitions among the first-tier ion-pair states of the I2 molecule excited to the E 0g+, vE = 8, 13, 19;JE ≈ 55 rovibronic levels in collisions with M = CD3I and CH3COCH3. It is shown that I2 (E over(→, M) D) near-resonant transitions are caused by the interaction between the transition dipole moment of I2(E-D) and the permanent electric dipole moment of M. The I2(D) state vibrational levels populated due to polarization interaction accompanied by quasi-resonance excitation of the collision partner are also observed.
