Webbthe initiation chemistry (and dosimetry) to remain invariant and reproducible as the reagent system of interest is varied. One potential drawback of this situation is that the limiting rate of intermediate formation is usually con trolled by the concentration limit of the precursor species. In photolysis,

WebbIn chemistry, initiation is a chemical reaction that triggers one or more secondary reactions. Often the initiation reaction generates a reactive intermediate from a stable molecule which is then involved in secondary reactions. In polymerisation, initiation is followed by a chain reaction and termination. [1] References WebbIn addition, initiation chemistry plays a major role in controlling the reaction time, and therefore heat concentration and dissipation, which resulted in a higher absorbance peak as initiation chemicals concentration increased.
