Book Description
The vibrational relaxation times of HF(v = 3) and HF(V = 1) in the presence of F atoms have been measured in a slow-flow fluorescence cell at room temperature. The HF is pumped to vibrational levels v = 1, 2, and 3 by a pulsed HF laser. It was found that F atoms deactivate HF(V = 3) faster than they do HF(v = 1) by a factor of 20.8 + or - 2.0. This dependence of the deactivation rate coefficient on v agrees with that determined for the exothermic V-V or V-R, T deactivation of HF(V = 1 to 3) by N2, O2, D2 and HC1. (Author).

Book Description
The deactivation of HF(v = 1) and DF(v = 1) by H and D atoms was studied at 295 K by means of the techniques of laser-induced infrared fluoresence and isothermal calorimetry. The upper limits for the deduced rate coefficients are well-defined, but the lower limits are imprecise. The results of this study are compared with other experimental data and with trajectory calculations. Qualitative data are presented regarding the role of reactive, i.e., F-atom exchange, versus nonreactive collisions in the removal of the v = 1 level. A verification of the method was made by determining a rate coefficient for H + HCl(v = 1) that is in good agreement with a recent study.

Book Description
The rate of HF(v = 2 and 3) removal by H atoms was measured at T = 295 K. The measurements were performed by laser-induced fluorescence in a discharge flow tube in which H atoms were produced by a microwave discharge. The absolute H-atom concentrations were measured by isothermal calorimetry with a Pt wire coil as a catalytic probe. A small fraction of the injected HF(v = 0) was pumped first to HF(v = 1) and subsequently to HF(v = 2) and HF(v = 3) by the multiline output from a pulsed HF transverse excitation atmospheric (TEA) laser.

Book Description
Rate constants are calculated for the vibrational relaxation of H2(v = 1) by H-atoms. A classical three-dimensional trajectory calculation is carried out to determine if both reactive and nonreactive collisions play an important role in the dynamics of this reaction on a London-Eyring-Polanyi-Sato (LEPS) potential energy hypersurface. The results of this calculation are compared with available experimental data. (Author).

Book Description
Critical care medicine is an evolving speciality in which the amount of available information is growing daily and spread across a myriad of books, journals and websites. This essential guide brings together this information in an easy-to-use format. Up-to-date, relevant, and evidence-based information on the management of the critically ill is combined in one resource, ideal for the use of Intensive Care Units, High Dependency Units, acute medical or surgical wards, Accident and Emergency departments and operating theatres. The book is designed such that each subject will form a self-contained topic in its own right, laid out across two or four pages to facilitate the key aim of rapid and easy access to information. This makes the information included simple to find, read and absorb, so that the book can be consulted in the clinic or ward setting for information on the optimum management of a particular condition. With chapters written by internationally renowned critical care specialists and edited by the three of the leading figures in UK Critical Care, this book should be an essential resource for all critical care physicians.

Book Description
The topic of hydrogen in an on metals and alloys is important in a number ofdisciplines including solid-state physics, materials science, physical chemistry, and energy technology. This volume treats the dynamics of hydrogen in intermetallic compounds, surface properties, kinetics, and applications of metal hydrides in energy technology. In addition, selected experimental methods are described. The introductory chapter will enable non-specialists to gain an overall picture of the field and to appreciate the relevant scientific issue. The companion volume, Hydrogene in Intermetallic Compounds I, was published as Vol. 63 of Topics in Applied Physics.
