摘要：

A model for the temperature-dependent electronic quenching of NO A2 SIGMA+ is presented. The model is appropriate for collision partners having stable negative ions, which are predicted to have large quenching cross-sections. Colliders with relatively large negative electron affinities are predicted to have cross-sections that are near-zero at room temperature and can increase dramatically at very high temperatures. A negligibly small electronic quenching cross-section is predicted for collision partners having negative ions that are unstable on a collisional timescale. Results of the model are compared to experimentally measured cross-sections for a number of species of interest in combustion and aerothermodynamic applications.
