Flash spectroscopic and kinetic studies have been carried out on the charge-transfer complex of tetracyanoethy-Iene with tetrahydrofunn in a liquid paraffin solution at room temperature. The cise and decay curves in transient electronic absorption intensity have been observed with a common rate constant, corresponding to the anion radical of tetracyanoethylene and the trlpIet state of the charge-transfer complex, respectively. From the kinetic analysis it has been concluded that the ionic photodissociation of this complex takes place in its lowest excited triplet state. This dissociation mechanism has also been confirmed by employing a triplet energy transfer technique with which "ionic photosensitized-dissociation" phenomenon is observed. Furthermore, a few other examples of ionic photosensitizeddissociation are demonstrated in rigid glasses with typical weak charge-transfer complexes whose photodissociation processes are well-known '.
