Notes:
We have extended our kinetic data base for the A state of BiF to include SF6 as a collision partner. By applying a four level finite difference fitting routine to time-resolved fluorescence traces from v'=0–3, we have obtained rate coefficients for electronic quenching, and for vibrational relaxation within the A-state manifold. As was the case for our previous results in He and Ar, electronic quenching is slow in comparison to radiative decay. Vibrational relaxation does not show a simple v' dependence, but rather, for the levels examined, increases markedly for higher v'. Our results confirm the suitability of SF6 as a bulk diluent in the proposed NF/BiF chemical laser system.
