Vacuum Ultraviolet Spectroscopy Ii

This volume is for practitioners, experimentalists, and graduate students in applied physics, particularly in the fields of atomic and molecular physics, who work with vacuum ultraviolet applications and are in need of choosing the best type of modern instrumentation. It provides first-hand knowledge of the state-of-the-art equipment sources and gives technical information on how to use it, along with a broad reference bibliography.

Techniques of Vacuum Ultraviolet Spectroscopy was first published in 1967. In the three decades since, the techniques associated with vacuum ultraviolet spectroscopy have been greatly expanded. Originally published as two volumes in the serial "Experimental Methods in the Physical Sciences," Vacuum Ultraviolet Spectroscopy combines in one paperback volume information on the many advances in vacuum ultraviolet (VUV) research. In addition, the book provides students and researchers with concise reviews of the important aspects of designing experiments in the VUV region.This is the only comprehensive treatise describing the use of synchrotron and other light sources for research, along with the new technologies in optical elements, multilayers, mirror coatings, soft x-ray zone plates, VUV detectors, interferometric spectrometers, and subjects such as spectromicroscopy, lithography, and photon-induced fluorescence. Vacuum Ultraviolet Spectroscopy is an ideal handbook both for the beginner and for the experienced researcher in any field requiring the use of VUV radiation. Key Features* Detailed review of synchrotron radiation sources including undulators and wigglers* Comprehensive outline of monochromator design* Concise review of optics theory for multilayers, spectrometers, and zone plates* Information about other important VUV sources such as laser produced plasmas and Electron Beam Ion Trap (EBIT) sources* Applications such as spectromicroscopy, lithography, and fluorescence

It is probably safe to predict that the future of chemistry is linked to the excited states of molecules and to other short lived species, ions and free radicals. Molecules have only one ground state but many excited states. However large the scope of normal, ground state chemistry might be, above and beyond it lies the world of excited states, each one having its own chemis try. The electronic transitions leading to the excited states, either discrete of continuous, are examined in molecular elec tronic spectroscopy. Electronic spectroscopy is the queen of all spectroscopies: for if we have the resolution we have everything. Vnfortunately, the chemist who is interested in the structure and reactions of larger molecules must often renounce all that infor mation. The spectra are complex and often diffuse; resolution does not always help. To understand such spectra he must look at whole families of molecules; to some extent structural analogies help. Let us call this chemical spectroscopy and handle it with care. In order to understand the properties of molecules we also need theory. We know that molecular problems are, in principle, soluble by the methods of quantum mechanics. Present time quan tum chemistry is able to provide a nearly accurate description of not too large molecules in their ground states. It is probablY again safe to predict that the future of quantum chemistry is connected with molecular excited states or, generally spoken, the accurate handling of the open-shell problem.
