This final report updates and summarizes the research accomplished under this grant during the period of November 1, 1980 through October 31, 1983. We have emphasized investigations in the following areas photochemical mechanisms through the use of time-resolved laser flash spectroscopy Carbenes, radical pairs, ylides, singlet molecular oxygen and other high energy species Detailed and systematic determination of the absolute rate constants for the addition of carbenes to ethylenes Application of weak magnetic fields for controlling the reactivity of radical pairs in colloidal systems Ability of weak magnetic fields to dramatically influence the rate and molecular weights in emulsion polymerization.
