22. Ideally, it would have been better to measure process (i) directly but the 6-Å separation of the Na (Formula presented) and (Formula presented) lines and rate of FS changing collisions make such a measurement extremely difficult. We also attempted to measure this rate by multiphoton ionization of the collision fragments, but the signal was obscured by the molecular structure near the atomic resonances.
