A technique has been developed whereby a single glow curve measurement may lead to the determination of the trapping parameters E and S (the trap depth and frequency factor respectively) and the order of kinetics, without need of mathematical approximations, for first and second-order glow curves. This has been facilitated by using a hyperbolic heating profile. The technique measures tm (time to maximum intensity of glow curve). and ti (points of inflection on the rising and falling slopes). For first-order kinetics E gamma /k=1.925/D where D=t2-t1, gamma is the heating constant and k is the Boltzman constant, whilst for second-order kinetics E gamma /k=2.643/D. This analysis is developed further to include non-integer orders of kinetics, from which a technique is derived to uniquely determine the order of kinetics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
