Conformer-Specific Photodissociation Dynamics of CF2ICF2I in Solution Probed by Time-Resolved Infrared Spectroscopy

The photodissociation dynamics of CF2ICF2I in solution was investigated from 0.3 ps to 100 μs, after the excitation of CF2ICF2I with a femtosecond UV pulse. Upon excitation, one I atom is eliminated within 0.3 ps, producing a haloethyl radical having a classical structure: anti-CF2ICF2 and gauche-CF...

Zusammenfassung:	The photodissociation dynamics of CF2ICF2I in solution was investigated from 0.3 ps to 100 μs, after the excitation of CF2ICF2I with a femtosecond UV pulse. Upon excitation, one I atom is eliminated within 0.3 ps, producing a haloethyl radical having a classical structure: anti-CF2ICF2 and gauche-CF2ICF2. All the nascent gauche-CF2ICF2 radicals reacted with the dissociated I atom within the solvent cage to produce a complex, I2··C2F4, in
