Matrix radiolysis and photoionization of CFCl3. Infrared spectra of CFCl+2and the parent cation

摘要

The rsquo;rsquo;Freonrsquo;rsquo; compound CFCl3has been subjected to radiolysis and photoionization during condensation with excess argon at 15 K. Infrared spectra of the matrix samples identified stable and free radical products and new absorptions which are attributed to charged species. The molecular ion bands exhibited three different behavior patterns on filtered mercury arc photolysis: The most photosensitive bands, destroyed by 420ndash;1000 nm light, are assigned to the parent cation; several absorptions which photodissociated with 290ndash;1000 nm radiation are due to a molecular anionic species; and new bands reduced by 220ndash;1000 nm light are assigned to the daughter cation CFCl+2. The vibrational assignments were confirmed by carbonhyphen;13 substitution.
