Research Abstract

The study of isotope effects on the rates and products of chemical processes has long been useful in increasing chemists understanding of the detailed nature of chemical reactions. While chemists have been studying isotope effects, other scientists have been using these measurements to aid in their interpretation of observations of isotopic composition of 'natural systems such as paleoclimatology,. oceanic circulation, atmospheric chemical transformation mechanisms, igneous rock geothermometry and the, evolutionary historyy of the solar system.
On the basic of above background, several methods how to measure the exact rate constants of chemical reactions, and how to measure the small difference to the rate constants between isotopes of molecules were investigated in the present study. The following studies were carried out.
(1) Sensitivity of photoionization mass spectrometer was improved to factor 100.
(2) Isotope effects for the rates of reaction of methyl radicals with oxygen were determined.
(2) Isotope effects for the rates of reaction of methyl radicals with oxygen were determined.
(3) Rate constants for reactions of sulfur containing radicals with R02 radicals were determined.
