Vibrational Energy Transfer in Thermal Unimolecular Systems by the Diffusion Cloud Method. Cyclopropane

Book Description
The present paper presents data on the relative collision efficiencies of cyclopropane in N2, CO2, H2, and He bath gases using the diffusion cloud technique. Temperature dependence of the rate has also been measured between 975 - 1175 K. Since the diffusion constants increase at higher temperatures, it was necessary to extend the mathematical treatment presented in the earlier paper. A model given by Nevrovskii which employs reflections at the wall and a flat velocity (plug flow) profile has been considered. Efforts have been made to extend the treatment to the case of a laminar (parabolic) flow contour, with only partial success. However, the present results serve to illustrate the usefulness of this method for the study of unimolecular systems.
Vibrational Energy Transfer in Unimolecular Reaction Systems

Book Description
Quantitative vibrational energy transfer data for polyatomic molecules at high levels of excitation are available from experiment at temperatures below approximate 600 K. In the treatment of systems at higher temperatures, as in shock tubes, collision efficiencies are simply transferred from low to high temperature. The theory of Tardy and Rabinovitch and Lin and Rabinovitch predicts a marked decrease in efficiency with rise of temperature. Some existing unimolecular reaction shock data is examined and some difficulties in interpretation are shown to be alleviated if decreased magnitudes for vibrational energy transfer efficiencies are employed.

Theory of Unimolecular Reactions

Pages : 464
Book Description
Theory of Unimolecular Reactions provides a comprehensive analysis of the theory of unimolecular reactions, also known to kineticists as the Rice-Marcus or the Rice-Ramsperger-Kassel-Marcus theory, and to those working in mass spectrometry and related fields as the quasi-equilibrium theory or the theory of mass spectra. This book demonstrates how theoretical parameters are related to experimental observables and describes the methods that are used to obtain useful numerical answers. This monograph consists of 11 chapters and begins by explaining the derivation of the expression for the basic rate k(E), with emphasis on the unimolecular rate constant, intramolecular energy transfer, and potential energy surfaces in unimolecular reactions. The statistical calculation of unimolecular rate under vibrational potential is also given, along with pertinent degrees of freedom. The remaining chapters explore the energy distribution functions appropriate to each system, the averaging of k(E), and the relations between theoretical and experimental parameters. Thermal reactions, chemical activation systems, and the theory of mass spectra are examined. The last chapter is devoted to the transition state and its ambiguities. This text will be of interest to gas kineticists, mass spectrometrists, and students and researchers working in the field of physical chemistry.

Book Description
Unimolecular Kinetics: Part 2: Collisional Energy Transfer and the Master Equation, Volume 43 in Elsevier’s Comprehensive Molecular Kinetics series, addresses collision energy transfer and the effects it has on gas phase reactions, particularly at low gas density. Such systems include combustion, industrial gas phase processes and atmospheric/environmental processes. The book also discusses The Master Equation to give a good overview of the mechanics underpinning unimolecular kinetics. This new volume will be of interest to researchers investigating gas phase processes which involve unimolecular reactions and the related intermolecular reactions. Discusses collision energy transfer and the effects it has on gas phase reactions Introduces stochastic techniques to energy transfer methods, allowing for an extension of the unimolecular theory beyond simple molecular dissociation Draws an important connection between detailed reaction dynamic studies and the rate of coefficient determination
