Research in chemical kinetics. Progress report, May 1, 1990--December 31, 1992

The following were studied: reactions of thermal {sup 38}Cl atoms (tests for heavy-atom blocking hypothesis with tetravinyl tin and the substrate reacted with {sup 38}Cl; reactions of thermal {sup 38}Cl with tetramethyl tin; reactions of thermal {sup 38}Cl with Si(CH{double_bond}CH{sub 2}){sub 4}[possible test for Si as a heavy -atom blocking agent in energy transfer]; rate constants for thermal {sup 38}Cl addition to olefinic positions), reactions of thermalized tritium atoms from nuclear recoil (thermal tritium atom addition to 3-chloropropene; thermal tritium atom reactions with propene; thermal tritium atom reactions with tetra-allyl tin and trimethylbutenyl tin), and hydrolysis of sulfur compounds in aqueous systems including the ocean (abstract only). Details of the research are reported in each section, except the latter; abstracts of published or submitted papers are also given
