Gas Phase Chemical Reachtion Systems consists of edited papers presented at the International Symposion Gas Phase Chemical Reaction Systems: Experiments and Models 100 Years after Max Bodenstein, held at Heidelberg. It is divided into six sections, reflecting the diversity of the topics discussed. Part I is devoted to experimental reaction dynamics studies employing laser and molecular-beam techniques. Part II is the theoretical counterpart of Part I. Part III summarizes the current status of the Bodenstein (H2+I2) "textbook reaction" with experimental and theoretical results. Part IV shows the different approaches for the calculation of state-specific and thermal rate data. Part V includes papers from the "heterogeneous reactions" session and Part VI is devoted to the mathematical modelling of turbulence, reactive flows and complex chemical reaction systems.

Klappentext

This volume consists of edited papers presented at the International Symposion Gas Phase Chemical Reaction Systems: Experiments and Models 100 Years After Max Bodenslein, held at the Internationales Wissenschaftsforum Heidelberg (IWH) in Heidelberg during July 25-28, 1995. The intention of this symposion was to bring together leading researchers from the fields of reaction dynamics, kinetics, catalysis and reactive flow model­ ling to discuss and review the advances in the understanding of chemical kinetics about 100 years after Max Bodenstein's pioneering work on the "hydrogen iodine reaction", which he carried out at the Chemistry Institute of the University of Heidelberg. The idea to focus in his doctoral thesis [1] on this reaction was brought up by his supervisor Victor Meyer (successor of Robert Bunsen at the Chemistry Institute of the University of Heidelberg) and originated from the non­ reproducible behaviour found by Bunsen and Roscoe in their early photochemical investigations of the H2/Cl2 system [2] and by van't Hoff [3], and V. Meyer and co-workers [4] in their experiments on the slow combustion of H2/02 mixtures.
