Book Description
[Truncated] Ion-molecule clusters comprising a halide anion 'core' solvated by neutral molecules in the gas phase are characterised using anion photoelectron spectroscopy and ab initio computational techniques. These clusters are of interest in studying the e ects of di erent solvent molecules on small anion cores, as transition states in reactions and are of atmospheric relevance. Many of these have not previously been investigated using the techniques employed in this work, as such the results presented here are novel. The mass and photoelectron spectra obtained for this dissertation include Cl-...(N2)n, Br-...(N2)n, I-...(N2)n, Br-...(N2O)n, Cl-...(NO)n, Br-...(NO)n and I-...(NO)n. The spectra were recorded using a home-built time-of- ight photoelectron spectrometer coupled to a time-of- ight mass spectrometer. Although the photoelectron spectra are of low resolution, the stabilisation energies and electron anities for these clusters of interest have been extracted. These are compared to analogous studies from the literature, such as the uoride clusters. The limits for the rst solvation shell of each of the clusters were determined to be larger than the sizes of the clusters under investigation here.

Book Description
Cluster Materials is the fourth volume of the highly successful series Advances in Metal and Semiconductor Clusters. In this volume the focus is on the properties of clusters which determine their potential applications as new materials. Metal and semiconductor clusters have been proposed as precursors for materials or as actual materials since the earliest days of cluster research. In the last few years, a variety of techniques have made it possible to produce clusters in sizes varying from a few atoms up to several thousand atoms. While some measurements are performed in the gas phase on non-isolated clusters, many cluster materials can now be isolated in macroscopic quantities and more convenient studies of their properties become possible. In this volume the authors focus on measurement of optical, electronic, magnetic, chemical and mechanical properties of clusters or of cluster assemblies. All of these properties must fall into acceptable ranges of behaviour before useful materials composed of clusters can be put into practical applications. As evidenced by the various work described here, the realisation of practical products based on cluster materials seems to be approaching rapidly.
Physical Chemistry of Cold Gas-Phase Functional Molecules and Clusters

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.
