Available in PDF, EPUB and Kindle. Book excerpt: Measurements have been made of the total radiation intensity from free jets of carbon dioxide and carbon that were excited in the source by a corona discharge. The radiation per molecule, obtained from the ratio of total intensity to source density, increases sharply when source temperature and pressure are such as the produce clustering in a jet of unexcited gas. We believe this enhancement may be due to interaction between aligned dipoles in adjacent cluster molecules. Measurements of the terminal rotational temperature of carbon monoxide and CO2, both pure in admixture with each other and/or argon indicate that CO always relaxes more slowly. There is no evidence of coupling between the rotational modes of the two species.

Available in PDF, EPUB and Kindle. Book excerpt: R. G. Cooks This introduction has three purposes: (a) to summarize some of the chief features of energy spectrometry of ions and to sketch in a little of the background to this subject, (b) to present some simple facts about collision processes which one skilled in, say, mass spectrometry but innocent of any knowledge of bimolecular collisions might find of value, and (c) to indicate the scope and content of the volume. 1. The Subject This book takes as its subject, ion-molecule and ion-atom reactions occurring at high energies. It emphasizes the study of inelastic reactions at high energy through measurements of translational energy. The investiga tion of these reactions using other procedures has been important in the cases of the simpler systems. In particular, the emitted radiation has been investigated and this subject is therefore discussed where appropriate. For more complex species, however, there is little information available other than from energy spectra. The defining characteristic of the energy range of interest is that momentum transfer to the neutral target is negligible for small scattering angles. The result of this apparently bland condition is a welcome simplicity in the interpretation of the results of what appears to be developing into a R. G.

Book excerpt: This research is carried out as part of the Gas-Phase Molecular Dynamics program in the Chemistry Department at Brookhaven National Laboratory. Chemical intermediates in the elementary gas-phase reactions involved in combustion chemistry are investigated by high resolution spectroscopic tools. Production, reaction, and energy transfer processes are investigated by transient, double resonance, polarization and saturation spectroscopies, with an emphasis on technique development and connection with theory, as well as specific molecular properties.

Available in PDF, EPUB and Kindle. Book excerpt: The only comprehensive guide to CIMS applications in structural elucidation and analytical studies Chemical Ionization Mass Spectrometry, 2nd Edition, provides a comprehensive, up-to-date review of CIMS applications in structural elucidation and quantitative analytical studies. For the benefit of readers without a background in gaseous ion chemistry, a thorough review is presented in Chapter 2. Other chapters discuss such topics as reagent ion systems within the context of the thermochemistry and kinetics of the ionization process, including reactions and the type of information obtained; isotopic exchange reactions; stereochemical effects in chemical ionization; and reactive ion/molecule collisions in quadrupole cells. Chemical ionization mass spectra of 13 classes of compounds are discussed in detail to illustrate the influence of different functional groups on the spectra observed. Chemical Ionization Mass Spectrometry, 2nd Edition will be a valuable reference for anyone interested in mass spectrometry and gaseous ion chemistry in general.

Available in PDF, EPUB and Kindle. Book excerpt: Details the many benefits of applying mass spectrometry to supramolecular chemistry Except as a method for the most basic measurements, mass spectrometry (MS) has long been considered incompatible with supramolecular chemistry. Yet, with today's methods, the disconnect between these two fields is not warranted. Mass Spectrometry and Gas-Phase Chemistry of Non-Covalent Complexes provides a convincing look at how modern MS techniques offer supramolecular chemists a powerful investigatory toolset. Bringing the two fields together in an interdisciplinary manner, this reference details the many different topics associated with the study of non-covalent complexes in the gas phase. The text begins with brief introductions to supramolecular chemistry and such relevant mass spectrometric methods as ionization techniques, analyzers, and tandem MS experiments. The coverage continues with: How the analyte's transition into the gas phase changes covalent bonding How limitations and pitfalls in analytical methods may produce data misinterpretations Artificial supramolecular aggregates and their examination Biomolecules, their complexes, and their examination After the general remarks making up the first section of the book, the following sections describe specific experimental procedures and are illustrated with numerous examples and short tutorials. Detailed citations end each chapter. Mass spectrometrists, supramolecular chemists, students in these fields, and interested readers from other disciplines involving the study of non-covalent bonds will all value Mass Spectrometry and Gas-Phase Chemistry of Non-Covalent Complexes as an innovative and practical resource.
