By the time Halcion was identified as the chemical source of his problem and Nichols stopped taking it, he had learned, he says, "what people are like when you're not so shiny and you don't have your powers".
The chemical source terms are implicit in time to allow for stiff chemical mechanisms.
The chemical source terms are evaluated based on tabulated chemistry incorporating detailed chemical kinetics.
