Professor Schuler received his B.S. from Canisius College in 1946 and his Ph.D. from Notre Dame in 1949. He returned to Canisius College as an assistant professor in 1949. From 1953 to 1956 he was an associate chemist at Brookhaven National Laboratory. In 1956 he became director of the Radiation Research Laboratories of the Mellon Institute. In 1976 he became director of the Radiation Laboratory at Notre Dame and professor in the Department of Chemistry. He is a fellow of the American Association for the Advancement of Science.
Professor Schuler's research interests focus on chemical intermediates produced photochemically and by ionizing radiation. To a large extent these intermediates are free radicals that can be studied directly by optical absorption, Raman and ESR spectroscopy. Of particular interest is the detailed structural and kinetic information that can be derived from these direct experiments. Information on reaction schemes and reaction rates can also be obtained indirectly by examination of the yields of radiation produced products. Radio-chemical and chromatographic methods are particularly useful here since they permit measurements to be made at very low product concentrations (10-7-10-3 M) so that initial processes can be studied.
Information on the lifetimes of ions and radicals produced in radiation chemical events can frequently be derived from studies on the dependence of the yields of products on reactant concentration. Currently Professor Schuler is examining the optical and ESR spectra of radicals produced in aqueous solution by the reactions of H atoms, OH radicals and hydrated electrons. A recent development is the use of resonance Raman spectroscopy to examine the vibrational modes of radicals. Analysis of products by aqueous liquid chromatography also gives information on the relative importance of the different modes of attack by these primary intermediates. Radio-chemical tracer experiments, in conjunction with gas and liquid chromatography, are used to advantage in examining the radiation chemistry of both aqueous and nonaqueous systems. In general, it is found that radiation chemical methodology can be applied in many types of problems to acquire information of broad chemical interest.
