(1) Under a current DOE contract, versatile experimental and computer modeling capabilities have been developed to study the isotopically selective, two-step, laser photodissociation of small molecules. This report reviews our progress on this problem and also provides an overview of an extensive study of two-step photodissociation of OCS conducted over the past 2 to 3 years. The report emphasizes investigations of the vibrationally state specific photophysics of OCS and relates the results to experimentally observed isotope enrichments. (2) This document is a proposal for a one year Research Grant to study laser isotope separation in cryogenic solutions. The study is a continuation and expansion of an effort in this area initiated under a current DOE contract. The proposed program of research is directed at measuring isotope enrichments obtained by two-step laser photodissociation of triatomic molecules, such as OCS and N/sub 2/O, dissolved in liquid cryogenic solvents, such as l-O/sub 2/, l-N/sub 2/ and liquefied rare gases. Fundamental optical and kinetic processes which underlie the isotope separation process will be investigated.
