Photoionization Studies of CCl₄ Using Synchrotron Radiation: The Measurements of Ionic Formation Enthalpies and Bond Energies

The photoionization and photodissociative ionization processes of CCl₄ have been investigated under the supersonic beam conditions using synchrotron radiation. The experimental results show that the parent ion is extremely unstable. Based on the measured appearance potential （AP） of the ionic fragments from the photodissociation ionization of CCl₄, the related ionic formation enthalpies, the bond dissociation energies （BDE） of ionic and neutral species,the dissociation energies （DE） of parent ion have been evaluated. The most possible channels of dissociative photoionization and other probably kinetic processes have been analyzed.
