Available in PDF, EPUB and Kindle. Book excerpt: Many biological and environmental systems contain ion, water, and hydrophobic components; and it is the balance between these competing interactions which governs their chemistry. This Thesis aims at exploring ion0́Ø0́Ø0́Øhydrocarbon interactions, then ion0́Ø0́Ø0́Øwater0́Ø0́Ø0́Øalkane interactions. To accomplish this, a combination of gas phase infrared predissociation spectroscopy (IRPD) and tandem mass spectrometry is utilized. The solvation of alkali metal ions by methane is discussed first, beginning with the effects of multiple argon atoms on Li+0́Ø0́Ø0́ØCH4 dimer clusters followed by a study of M+(CH4)n clusters where it is revealed that ions have a weak electrostatic effect beyond the first solvent shell. Next, the argon tagging and monitoring unique fragmentation channels are used to selectively probe for high energy Li+(H2O)3-4Ar1 conformers which contain extensive water hydrogen bonding. Finally, ion0́Ø0́Ø0́Øwater0́Ø0́Ø0́Øalkane interactions are probed in Li+(H2O)n clusters containing CH4 or C6H12 molecules. Some spectra contain hydrogen bonded peaks correlating to weak water0́Ø0́Ø0́Øalkane interactions. Furthermore, there is strong evidence that high energy conformers containing water hydrogen bonding are present in the cluster ion beam. This analysis is expanded to anionic Cl-(Water)m(CH4)n clusters to compare with cations. Density functional theory or MP2 level calculations were used to support and help characterize experimental data.

Available in PDF, EPUB and Kindle. Book excerpt: Infrared spectroscopy, coupled with mass spectrometry has been used to investigate a specific sized gas phase clusters. In particular, alkali metals i.e. lithium or lanthanides such as ytterbium in the presence of ammonia derivative solvents, has been explored observing both the electronic and vibrational spectral characteristics. Ab initio work has been carried out in support of experimental work which has given some vital clues to help assign some spectra. Firstly, the first electronic spectrum of Li(NH3)4has been observed. Strong absorption is observed in the near-infrared and the band system is assigned to the Ã2T2-X-tilde2A1 transition in the tetrahedral complex. The vibrational structure is indicative of a substantial Jahn-Teller effect in the excited electronic state. Following this, LiNH3 was the next complex to be investigated, the spectra is consistent with two electronic transitions in close proximity, the Ã2E-X-tilde2A1 and B-tilde2A1-X-tilde2A1 systems. Vibrational structure is seen in both systems and the prominence of a particular band is attributed to a Herzberg-Teller coupling. The electronic spectrum of the Li-methylamine cluster was attempted, this spectrum occurrs in the near-infrared and shows provisional bands assigned to the Ã2A-X-tilde2A 0-superscript0-subscript0, B-tilde2A-X-tilde2A 0-superscript0-subscript0 and possibly the C-tilde2A-X-tilde2A 0-superscript0-subscript0 electronic transitions. An effort was made to try and record the IR depletion spectrum of a mixed cluster, such as Li(NH3)n(Ma)m, despite the additional bulk of the methylamine group, up to four solvent molecules were able to reside within the first solvation shell. Finally, the electronic spectrum of the rare earth complex, YbNH3 has been recorded using two colour resonance-enhanced multiphoton ionisation spectroscopy (REMPI). The spectrum arises from a spin-forbidden transition between the 1A1 ground electronic state and a 3E excited electronic state. Some vibrational structure is also observed in the REMPI spectrum which has been assigned.

This book was released on 2012-12-06 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: We believe this to be the first monograph devoted to the physicochemical properties of solutions in organic solvent systems. Although there have 1 been a number of books on the subject of non-aqueous solvents - 4, they have been devoted, almost entirely, to inorganic solvents such as liquid ammonia, liquid sulphur dioxide, etc. A variety of new solvents such as dimethylformamide, dimethylsulphoxide and propylene carbonate have become commercially available over the last twenty years. Solutions in these solvents are of technological interest in connection with novel battery systems and chemical synthesis, while studies of ion solvation and transport properties have fostered academic interest. This monograph is primarily concerned with electrolytic solutions although discussion of non-electrolyte solutions has not been excluded. We have deliberately omitted consideration of the important area of solvent extraction, since this has been adequately covered elsewhere. Our contributors were asked to review and discuss their respective areas with particular reference to differences in technique necessitated by use of non-aqueous solvents while not reiterating facts well-known from experience with aqueous solutions. We have striven to build their contributions into a coherent and consistent whole. We thank our con tributors for following our suggestions so ably and for their forebearance in the face of our editorial impositions.

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: This product is not available separately, it is only sold as part of a set. There are 750 products in the set and these are all sold as one entity. Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Download or read book Infrared Spectroscopy of Cluster Ions: High Energy Conformer Trapping and Multiple Photon Absorption written by Jordan P. Beck and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared predissociation (IRPD) spectra of several cluster ions are presented, resulting in the emergence of two major themes. Trapped, high energy conformers are observed in argon tagged clusters. In non-argon tagged hydrated alkali metal ion clusters, multiple photon absorption processes can occur. The cluster ions discussed in this dissertation are generated by impacting neutral clusters with ions. If there is an energetic barrier between the neutral cluster configuration and the global minimum cluster ion configuration that is larger than the binding energy of the most labile ligand, then high energy conformers can be trapped. Thus, the trapped conformers retain some of the bonds of their neutral precursors. For example, neutral methanol dimer contains a hydrogen bond and a trapped, high energy Cl (CH3OH)2Ar conformer was observed which also contains a methanol0́Ø0́Ø0́Ømethanol hydrogen bond. Similar results are reported for M+(C6H6)2-4(H2O)2Ar and M+(benzyl alcohol)1(H2O)1-2Ar where IRPD spectra reveal hydrogen bonds resulting from the configurations of the neutral precursors. For most of the clusters studied, spectral features from high energy conformers and global minimum energy conformers were observed in the same spectra. However, a special case is reported in chapter 5 in which spectral features from high energy conformers and global minimum energy conformers of Li+(C6H6)2-4(H2O)2Ar were observed in different spectra corresponding to the fragmentation channel monitored. This conformer specific fragmentation greatly simplified the interpretation of the spectra and provided useful information on the cluster energetics. Conformer specific fragmentation was also observed for M+(H2O)5-7, but for a different reason. In the hydrogen bonded O-H stretching region, IRPD spectra obtained by monitoring the loss of two waters only contained features from linear hydrogen bonds. This mode dependent fragmentation is believed to be the result of multiple photon absorption. This conclusion is supported by laser-fluence dependence studies and by evaporative ensemble calculations.
