Book excerpt: The problem of the bimolecular rate constant, alpha, for the mutual charge neutralization reaction (ion-ion recombination) for ions formed by the vacuum ultraviolet photolysis of nitric oxide is considered. The pressure dependence of alpha over a pressure range of 10 to 600 torr for mixtures of a few hundred microns of NO with He, Ar, Kr, Xe, H/sub 2/, D/sub 2/, and N/sub 2/ was measured. From the low-pressure limit of alpha, the rate constant for charge neutralization in the absence of a third body was found to be k/sub o/ = 2.1 plus or minus 0.4 x 10/sup -7/ cm/sup 3// sec. The high-pressure limit of alpha was estimated to be 2.0 plus or minus 0.5 x 10/sup -6/ cm/sup 3//sec. The third-body efficiencies for promoting the charge-neutralization reaction were measured. The results, relative to He as the third-body gas, are H/sub 2/= 1.4 plus or minus 0.4, D/sub 2/= 1.5 plus or minus 0.4, Ar =3.6 plus or minus 0.8, Kr =4.3 plus or min11.0, N/sub 2/ = 5.2 plus or minus 1.1, and Xe = 6.8 plus or minus 1.5. The average ionic mobility in the gas mixtures is estimated, and the mobilities indicate that at least some of the ions must be present as ion clusters. It is shown that the addition of NO/sub 2/ or H/sub 2/O further lowers the mobility. A detailed calculation of the three-body charge-neutralization process was made using a computer. This calculation considers that the rate of charge neutralization is the rate at which ion pairs are deactivated by collision with the neutral gas molecules to form ion pairs that cannot separate to large distances. The potential between the ions and the neutrals is assumed to be an ion-induced dipole potential with a hard-sphere core. The calculation involves an average over the various angles in the collisions. The predicted values of alpha depend on a parameter of the calculation, but over a wide range of this parameter the predicted relative third-body efficiencies are in reasonable agreement with the experimental values.

Download or read book Fundamentals of Ionized Gases written by Boris M. Smirnov and published by John Wiley & Sons. This book was released on 2012-09-19 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and readily accessible work for studying the physics of ionized gases, based on "Physics of Ionized Gases". The focus remains on fundamentals rather than on the details required for interesting but difficult applications, such as magnetic confinement fusion, or the phenomena that occur with extremely high-intensity short-pulse lasers. However, this new work benefits from much rearranging of the subject matter within each topic, resulting in a more coherent structure. There are also some significant additions, many of which relate to clusters, while other enlarged sections include plasmas in the atmosphere and their applications. In each case, the emphasis is on a clear and unified understanding of the basic physics that underlies all plasma phenomena. Thus, there are chapters on plasma behavior from the viewpoint of atomic and molecular physics, as well as on the macroscopic phenomena involved in physical kinetics of plasmas and the transport of radiation and of charged particles within plasmas. With this grounding in the fundamental physics of plasmas, the notoriously difficult subjects of nonlinear phenomena and of instabilities in plasmas can then be treated with comprehensive clarity. The work is rounded off with appendices containing information and data of great importance and relevance that are not easily found in other books. Valuable reading for graduate and PhD physics students, and a reference for researchers in low-temperature ionized gases-plasma processing, edge region fusion plasma physics, and atmospheric plasmas.

Formation of negative ions by processes other than attachment in the gaseous phase at low X/po 17. Introduction. As early as 1912, J. J. THOMSON [32J in his first mass spectro graph observed negative ions of 0-, Cl-, H- and what he believed to be N-. He at first ascribed these to possible dissociation of polar gaseous compounds by electron impact but control studies using ionization at low energies in glow discharges indicated that this was not the origin. O. W. RICHARDSON [33J in his book on emission of electricity from hot bodies reported negative ions to come from hot salts. From there on many experimental studies over the years indicated that negative ions could be formed by various processes. By the middle nineteen hundred and thirties the data fairly clearly identified several processes as being active and MASSEY and SMITH [34J developed the theory underlying some of them. More data are summarized in MASSEY'S excellent little monograph on Negative Ions and in )L\SSEY and BURHOP'S recent book [35]. Since that period, stimulated by various investigations and certain industrial problems, very careful studies of the appearance of such ions by mass spectrograph have been carried out in the laboratory of K. G. EMELEUS in Belfast by SLOANE and his co-workers [3J that haw clarified the questions and indicated what ions have been observed and something of the processes at work.

This book was released on 2013-10-22 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinetics and Dynamics of Elementary Gas Reactions surveys the state of modern knowledge on elementary gas reactions to understand natural phenomena in terms of molecular behavior. Part 1 of this book describes the theoretical and conceptual background of elementary gas-phase reactions, emphasizing the assumptions and limitations of each theoretical approach, as well as its strengths. In Part 2, selected experimental results are considered to demonstrate the scope of present day techniques and illustrate the application of the theoretical ideas introduced in Part 1. This publication is intended primarily for working kineticists and chemists, but is also beneficial to graduate students.
