Abstract

The mechanism for the dissociation of several haloaromatic molecules has been investigated by means of absorption and emission picosecond spectroscopy. It is found that the rates of intersystem crossing and dissociation increase from chloro to bromo to iodo substituents. It is observed that the position of the halo substituent and temperature influence these rates. A model for the dissociation mechanism is proposed which is consistent with the absorption and emission data presented.
