✦ Synopsis

The relative efficiencies for two dissociative channels in the vacuum W phot lysis of carbony sulphide have been datermined using the flash photolysis-resonance fluorescence technique to mea.s~ .e initial yields of atomic osygal and atomic suIpl~.~r. At wav~:lengt!ls above 105 nm, the dissociation of QCS to form atomic sulphur exceeded that for the formation of atomic oxygen lo zuch an extent that only an upper limit could be placed on the minor process, Qls 2 50 @o. In addition, the flash photo-escitation ofc~bonyl sulphide produced a Iong-lived spontanaous emission in the UV and vacuum UV that ITl@ht be due to molecular fluorescence from OCS.

Resonance-enhanced photoionization has been used to follow S(3P,) in the photodissociation of CS, at 193 nm. The contributions from initial photodissociation and from S('D) relaxation have been resolved and give a (15 f 5)X yield of S('D). The possibility of secondary production of S(3P,) by CS phot
