Abstract One of the myriad reactions of interest in the combustion of motor fuels is the addition of an oxygen atom in the 3 P state to cyclopentadiene. The generally accepted mechanism for the reaction begins with addition of the atom to a double bond, and formation of one or the other of two triplet diradicals depending on the point of addition. These can both undergo intersystem crossing to form singlet diradicals which pass through different transition states to the product, 2- or 3-cyclopentenone.

In a detailed study of an enzyme reaction pathway, a measured composite rate constant, for example, kcat, can be interpreted in ways that lead to ambiguous conclusions. Two conditions must be met to solve this problem: (1) an elementary rate constant must be measured, and (2) a maximum number of physical-chemical parameters must be used to perturb the system under study. To gain access to elementary rate constants, cryobaroenzymology and/or transient methods, such as stopped-flow and flow-quench kinetics, can be used.
