- 中文摘要: The highly versatile OODR-MPI technique is used, mostly without resort to isotope tagging, to study the quantum state specific rovibronic energy transfer between molecules of the same species, specifically CO(A)-CO(X). Two types of rovibronic energy transfer mechanisms are found to be prevailing and are differentiated experimentally, i.e., the long range near resonant dipole-dipole interactions and the short range exciplex formation. The first type is characterized, at first unexpectedly, by its compliance to the selection rules of optical dipole transitions,.DELTA.J=0, .plmin.1 and parity +.arrl..arrr.-. Numerical computation procedures are presented for the calculation of rovibronic energy transfer cross-sections when the two types of mechanism are operating concurrently. The computed results and their variation with J are in good accord with the experiments.
