✦ Synopsis

Charge exchange of neutral C,F, by a variety of atomic and molecular ions in tbe 1 to 25 eV range of collision energies is used to characterize the energies associated with formation of lC3F6)+'. The internal energy of the nascent (C,F,I+' ion, assessed by observing the degree to which it fragments, increases with the recombination energy of tbe charge-exchange reagent. The existence of excited states of the reagent ions is identified from the fragmentation behaviour of IC,F61+' in the cases of lCS21+', NO+, O:., (NH,I+' and possibly lCH,l+'. In addition, the data confirm that the IC,F,I+' parent ion fragments from both the ground state and a long-lived isolated electronic state. The latter is populated by near-resonant charge transfer. Translational excitation contributes relatively little to internal excitation of the charge-exchanged product ion and even less in the case of the isolated state.

Photodissociation spectra of (C,H,): are measured in the 700-1400 nm range. The charge resonance (CR) bands characteristic of (C,H,): are found to be kept almost intact in (C,H,)$; the spectra show the main band at z 960 nm and relatively weak one at =Z 1220 nm. The photodissociation cross section
