    • The observed resonant enhancement via a two‐photon state of neutral I atoms implies that our experiment probes the dynamics of some dissociation channel where neutral iodine atoms are produced. Pathways that lead directly to [Formula Omitted] ions would be manifested in the background signal since the signal from such a channel does not depend on the time delay between pump and probe pulses. A similar point has been discussed in some detail previously (Ref. 1, Knee et al.).

    • passing, it may be noted that a united atom model using the mass of [Formula Omitted] instead of the bare C atom predicts 44% of the available energy should appear as translation, a value which is much closer to the observed value. This approach corresponds to having the C‐F bonds of the α carbon atom being rigid, while the rest of the radical is flexible.

    • The threshold for dissociation of [Formula Omitted] was calculated using the following thermochemical parameters. Heats of formation at [Formula Omitted] I (25.63 kcal/mol), [Formula Omitted] [Formula Omitted] These values were all obtained from Ref. 9.

    • It may be worth recalling our earlier comment on how excitonic interactions may possibly affect the energy at which the states cross.
