Book Description
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.

Book Description
Atomic Clusters: From Gas Phase to Deposited brings together a series of chapters, prepared by acknowledged experts in their fields. Both fundamental and practical aspects are addressed of the physics and chemistry of a novel state of matter, namely clusters of small numbers of atoms of nanometre dimensions. This is a field of nanoscience that existed before the word was invented, but has particularly achieved major advances in the recent years. * Contributions from leading experts in solid surfaces research* Cluster science is concerned with the properties of materials on the nano-metre scale* Brings together work on both free (gas-phase) clusters and those deposited on surfaces
Gas-phase IR Spectroscopy and Structure of Biological Molecules

Languages : en
Pages : 406
Book Description
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.

Book Description
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.
