Photooxidation of dimethyl sulfide and dimethyl disulfide. II: Mechanism evaluation


The mechanisms for atmospheric photooxidation of CH₃SCH₃ and CH₃SSCH₃ developed in Part I are evaluated by a series of outdoor smog chamber experiments. Measured product yields, including SO₂, H₂SO₄, CH₃SO₃H and HCHO, are reported. The predictions of the mechanisms developed in Part I are found to be in substantial agreement with the measured concentrations from the smog chamber. By comparison of mechanism predictions and observations, critical uncertainties in the mechanism are identified.
