摘要

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 ;J_E ≈ 55 rovibronic levels in collisions with M = CD₃I and CH₃COCH₃. It is shown that 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.
