Abstract

The photodissociation dynamics of OClO in room temperature water solution were investigated using picosecond transient absorption spectroscopy. The time dependent data are consistent with the conclusion that following excitation at 355 nm, 90% of the OCIO molecules photodissociate forming ClO and 0 and 10% isomerize forming CIOO. The photochemically generated CIOO thermally decomposes into Cl and 0₂ with a rate constant of -6.7 x 1O⁹ s^-1.
