    This study introduces a new method for generating hydrogen atoms in solution via thiol photolysis. It provides the first kinetic study of hydrogen atoms generated without ionizing radiation, yielding new rate constant data for organic compounds.

    Area of Science:

    • Physical Chemistry
    • Photochemistry
    • Chemical Kinetics

    Background:

    • Hydrogen atoms are crucial reactive intermediates in various chemical processes.
    • Previous kinetic studies often relied on ionizing radiation (radiolysis) to generate hydrogen atoms.
    • A non-radiolytic method for generating hydrogen atoms in solution was needed for comparative kinetic studies.

    Purpose of the Study:

    • To develop and apply a novel method for generating hydrogen atoms in solution using thiol photolysis.
    • To conduct the first kinetic study of hydrogen atoms generated via photolysis, not ionizing radiation.
    • To measure the relative rate constants (k(H)) for the reaction of hydrogen atoms with organic compounds (QH).

    Main Methods:

    • Generation of hydrogen atoms in solution through the photolysis of thiols.

  • Measurement of relative rate constants for the reaction H* + QH --> H(2) + Q*.
  • Comparison of photolysis-derived rate constants with existing radiolysis data.

    • Main Results:

    • Successfully generated hydrogen atoms in solution using thiol photolysis.
    • Determined relative rate constants for hydrogen atom reactions with various organic compounds.
    • Observed agreement with radiolysis data for most compounds, but significant differences for some.

    Conclusions:

    • Thiol photolysis provides a viable, non-radiolytic method for generating hydrogen atoms in solution for kinetic studies.
    • The study highlights the first kinetic investigation of photolytically generated hydrogen atoms.
    • Discrepancies in rate constants for certain compounds suggest potential differences in reaction mechanisms or intermediate states between the two generation methods.
