Photodissociation of hypohalous acids: from fundamentals to atmospheric chemistry

摘要

Abstract: The photolysis of some hypohalous acids and related molecules has been investigated by observing the OH rotational distributions by laser induced fluorescence and Cl atoms by REMPI and time-of-flight techniques. The results are consistent with a rapid and direct dissociation process with most of the available energy going into relative translational motion of the products. Only a small degree of rotational and vibrational excitation of the OH fragment is observed. !21
