Abstract:

Quantum-state-specific collisional energy transfer has been studied in the N atoms, and the Hydroxyl and Nitrogen Sulfur diatomic radicals. Vibrational energy transfer VET in the A2 Sigma state of OH was found to depend on rotational level. Rotational energy transfer in A shows unusual propensities. The final vibrational level distribution following quenching of A2 Sigma is not governed by Franck-Condon considerations. VET in X2 Pi Sub i OH generally proceeds much faster than in A. Delta J - 1 transfer is fastest among the spin-orbit components of the 3P4 D0 state of N. Quenching of B2 Pi NS varies with vibrational level differently depending on collider. The amount of Delta V - 2 VET compared with Delta V - 1 also depends on v and collider. Keywords Molecule, Molecule interactions, Laser induced fluorescence.
