Vacuum Ultraviolet Photoionization And Photodissociation Of Molecules And Clusters

This monograph reviews the recent progress in vacuum ultraviolet (VUV) photoionization and photodissociation processes. Photoionization, photoelectron, and fluorescence spectroscopic techniques have played an important role in revealing the photoionization and photodissociation dynamics of molecules in the vacuum ultraviolet region and in providing accurate energetic and spectroscopic information of ions as well as neutral molecules. The book represents the first detailed review of major experimental developments in the studies of single vacuum ultraviolet photon ionization and dissociation processes of gaseous molecules and clusters.

Owing to the advances of vacuum ultraviolet and ultrafast lasers and third generation synchrotron sources, the research on photoionization, photoelectrons, and photodetachment has gained much vitality in recent years. These new light sources, together with ingenious experimental techniques, such as the coincidence imaging, molecular beam, pulsed field ionization photoelectron, mass-analyzed threshold ion, and pulsed field ion pair schemes, have allowed spectroscopic, dynamic, and energetic studies of gaseous species to a new level of detail and accuracy. Profitable applications of these methods to liquids are emerging.This invaluable two-volume review consists of twenty-two chapters, focusing on recent developments in photoionization and photodetachment studies of atoms; molecules, transient species, clusters, and liquids.

Leading investigators offer the first comprehensive study of gas phase photoionization research in the VUV and soft X-ray regime since the massive employment of synchrotron radiation as a spectroscopic tool. Chapters cover all aspects of photoionization phenomena from total cross sections to highly differentiated measurements such as coincidence experiments and spin-resolved electron spectroscopy. This work is abundant with illustrations.

The synchrotron light source is becoming widely available, after its evolution from its infancy in the sixties to the present third generation source with insertion devices. It is timely to examine the impact that synchrotron light has made and will continue to make on chemical research. With this objective in mind, the editor of this invaluable book invited contributions from practitioners who are in the forefront of the research. The book summarizes most of the significant developments in the last decade in chemical and related research using synchrotron light. The utilization of the light as a probe as well as an energy source is emphasized.This book is organized into two parts, in order of increasing photon energy. Part I deals with the applications of low energy photons and covers areas such as gas phase photodissociation reactions and dynamics, soft X-ray fluorescence, IR and photoemission analysis of surfaces, spectroscopy of organic and polymeric materials, catalysts, electronic and magnetic materials, and spectromicroscopy. Part II encompasses applications using soft to hard X-rays, including spectroscopy of surface and thin films, XAFS, diffraction and scattering, and several technological applications, namely the microprobe, photoetching and tribology.

When after three decades of research Singapore could produce its own water, the little city-state was said to have lost its vulnerability. No longer would every policy have to bend at the knees for water survival. It was finally time to celebrate liberty!When did the same moment come in Bala's life? Was it when in mid-Atlantic he heard of his promotion as Controller of Posts? Or was it when he was appointed by the President as member of the Parliamentary Elections Minority Committee? Or was it at a moment of tragic loss when he realised he had nothing more to lose?Singapore, My Country tells M Bala Subramanion's story, a second generation Indian who lost his father to the Death Railway, witnessed Subhas Chandra Bose at the Padang and later emerged as not only a senior civil servant but the man behind multiple social interventions, living in a fast evolving Singapore.The histories of the man and his nation remain seamlessly intertwined, each peppered with equal doses of endeavour, ingenuity and a sheer will to survive!
