This book was released on 2015-06-03 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.

This book was released on 2019-08-02 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes advanced research on the structures and photochemical properties of polyatomic molecules and molecular clusters having various functionalities under cold gas-phase conditions. Target molecules are crown ethers, polypeptides, large size protonated clusters, metal clusters, and other complex polyatomic molecules of special interest. A variety of advanced frequency and time-domain laser spectroscopic methods are applied. The book begins with the principle of an experimental setup for cold gas-phase molecules and various laser spectroscopic methods, followed by chapters on investigation of specific molecular systems. Through a molecular-level approach and analysis by quantum chemical calculation, it is possible to learn how atomic and molecular-level interactions (van der Waals, hydrogen-bonding, and others) control the specific properties of molecules and clusters. Those properties include molecular recognition, induced fitting, chirality, proton and hydrogen transfer, isomerization, and catalytic reaction. The information will be applicable to the design of new types of functional molecules and nanoparticles in the broad area that includes applied chemistry, drug delivery systems, and catalysts.

Available in PDF, EPUB and Kindle. Book excerpt: Optical spectroscopy combined with mass spectrometry provides a unique opportunity to probe the intrinsic properties of biologically-relevant ions in the gas phase, free from the interfering effects of solvent interactions in the condensed phase. Electrospray ionization allows large biomolecules to be transferred intact into the gas phase for mass analysis. Modern mass spectrometers provide excellent sensitivity, mass-resolution and can efficiently isolate a single ionic species from a complex mixture. However, the extent to which biomolecules retain their solution-phase conformations in the gas phase is largely unknown. Therefore, there is considerable interest in applying spectroscopic methods to biological ions in vacuuo. Due to the low number densities of ions in storage devices, traditional absorption measurements are not feasible, requiring more sensitive analytical methods. Two such techniques are laser-inducedfluorescence (LIF) and photo-dissociation (PD) action spectroscopy, both of which measure the consequence of absorption. The work in this dissertation describes applications of optical spectroscopic methods to interrogate mass-selected ions using a variety of ion storage apparatus including a Fourier transform ion cyclotron resonance mass spectrometer, a quadrupole ion trap and an electrostatic ion storage ring. First, the conformations of small cationized arginine complexes have been investigated using infrared multiple-photon dissociation (IRMPD) action spectroscopy in the IR fingerprint region of the spectrum (200-1800 cm-1). Second, an apparatus incorporating a quadrupole ion trap has been constructed in our laboratory to perform LIF and PD-action spectroscopy. The gas-phase fluorescence and photodissociation properties of three Rhodamine dyes have been investigated including fluorescence excitation and dispersed fluorescence spectra. Finally, the latter chapters describe the use of electronic action spectroscopy to investigate a model chromophore o.

Available in PDF, EPUB and Kindle. Book excerpt: When an analyte seeded in a high pressure inert gas is expanded into a vacuum chamber, an intense beam of molecular clusters is formed. The consequential skimming and ionization of the cluster beam allows for the analysis of molecular cluster ions using tandem mass spectrometry. Various process that occur within certain heterocluster ions, including reactivity and fragmentation pathways, may be observed by inducing collisions of the cluster ions with inert gas atoms. In certain situations, a reaction channel is only accessed when a minimum number of solvent molecules are present in a heterocluster ion. These reactions are "solvent catalyzed" in that a critical number of solvent molecules effectively lowers the activation barrier such that the reaction becomes the dominant process occurring within that cluster ion. A series of mass spectrometric investigations have been performed. The first was focused on formic acid/water cluster ions. It was found that the loss of a dimer was almost always preferred except when there were six formic acid molecules present in a cluster. The structure that was formed between these six formic acid molecules and the water was so preferred that it was extremely difficult for the dimer to be removed, so usually only one formic acid molecule would be removed. The second investigation focused on the reactivity of acetic acid/water cluster ions. It was discovered that the preferred cluster structure was that containing five acetic acid molecules with the water. The acetic acid/water clusters seemed to prefer the loss of a monomer unit. A third investigation performed was focused on the reactivity of acetic acid/ammonia cluster ions. It seems that once the cluster size is greater than six acetic acid molecules, the loss of a dimer is preferred to the loss of a monomer, this would make the clusters of six acetic acids and ammonia the magic number. A fourth investigation was between formic acid/ammonia cluster ions. No new surprises were discovered from this data.

Available in PDF, EPUB and Kindle. Book excerpt: The field of gas phase inorganic ion chemistry is relatively new; the early studies date back approximately twenty years, but there has been intense interest and development in the field in the last ten years. As with much of modern chemistry, the growth in gas phase inorganic ion chemistry can be traced to the development of instrumentation and new experimental methods. Studies in this area require sophisticated instruments and sample introduc tion/ ionization methods, and often these processes are complicated by the need for state-selecting (or collisionally stabilizing) the reactive species in order to assign the chemistry unequivocally. At the present level of experimental development, a wide range of experiments on diverse ionic systems are possible and many detailed aspects of the chemistry can be studied. Gas Phase Inorganic Chemistry focuses on the reactions of metal ions and metal clusters, and on the study of these species using the available modern spectroscopic methods. Three of the twelve chapters cover the chemistry of ionic monometal transition metal ions and the chemistry of these species with small diatomics and model organics. Two of the chapters focus on the studies of the chemical and physical properties of (primarily) transition metal clusters, and these chapters review experimental methods and capabilities. Two chapters also deal with the chemistry of transition metal carbonyl clusters, and these chapters address issues important to cluster growth and activation as well as the characterization of such species.
