The Theory of Absolute Reaction Rates and its Application to Viscosity and Diffusion in the Liquid State. Rate constants for the reaction of OH radicals and Cl atoms with CH 3 ONO 2, C 2 H 5 ONO 2, n-C 3 H 7 ONO 2, n-C 4 H 9 ONO 2, and n-C 5 H 11 ONO 2 have been determined at 298 ± 2 K and a total pressure of approximately 1 atm. The OH rate data were obtained using both the absolute-rate technique or pulse radiolysis combined with kinetic spectroscopy and a conventional photolytic relative-rate The absolute version of the purchasing power parity theory is, no doubt, quite simple and elegant, yet it has certain shortcomings.
