Photodissociation induced by the absorption of single photons permits the detailed study of molecular dynamics such as the breaking of bonds, internal energy transfer and radiationless transitions. The availability, over the last decade, of powerful lasers operating over a wide frequency range has stimulated rapid development of new experimental techniques which make it possible to analyse photodissociation processes in unprecedented detail. At the same time, theorists have developed powerful methods to treat this fundamental process, at least for small molecules, in an essentially exact...

Spectropolarimetry embraces the most complete and detailed measurement and analysis of light, as well as its interaction with matter. This book provides an introductory overview of the subject because it is playing an increasingly important role in modern solar observations. Chapters include a comprehensive description of the polarization state of polychromatic light and its measurement; an overview of astronomical polarimetry; and the formation of spectral lines in the presence of a magnetic field. The text is a valuable reference for graduates and researchers in astrophysics, solar physics...

This is an introduction to current high resolution NMR practice. It provides the physical background to NMR spectroscopy from the point of view of the whole periodic table rather than concentrating on the narrow applications of 1H and 13C NMR spectroscopy. Examples and many new problems, mainly from the recent inorganic /organometallic chemistry literature support the text throughout. Mathematics is kept to a minimum.

From Hiroshima to the Iceman: The Development and Applications of Accelerator Mass Spectrometry presents a fascinating account of a breakthrough in science and the insights it has brought that would not have been possible without it. Involved since its invention, Harry Gove recounts the story of the development of accelerator mass spectrometry and its use as an ultrasensitive detection technique in many fields of science and the arts. A key advantage of the technique is that it requires only very small samples of material. The book explores the areas where the technique has increased...

Mass Spectrometry (MS) has rapidly become an indispensable tool in polymer analysis, and modern MS today complements in many ways the structural data provided by Nuclear Magnetic Resonance (NMR) and Infrared (IR) methods. Recent advances have sparked a growing interest in this field and established a need for a summary of progress made and results achieved.
Mass Spectrometry of Polymers effectively fills this need. The discussion begins by introducing MS in detail, providing a historical perspective and a review of modern instrumentation and methods. The text then focuses on mathematical...

The purpose of this book is to collect into one volume the research done on the mass spectrometry of peptides. It balances a range of topics including theory, instrumentation, analytical techniques, and biological applications. The scope of the work contains three major sections: ionization methods, instrumental developments, and analysis of peptides. It describes 252Cf plasma desorption and laser-induced multiphoton ionization methodology. This exciting resource covers many new areas, including continuous flow FAB, quantification of human neuropeptides, and peptide mapping. It also discusses...

Offers a general problem-solving algorithm for determining the structure of a molecule from complementary spectra or spectral data obtained from MS, IR, NMR, or UV spectrophotometers. This title analyzes representative compounds. It is suitable for the analyst in interpreting organic spectra.

Providing a general introduction to the use of isotope dilution mass spectrometry (IDMS) technique for high accuracy measurements, this guide describes two specific methodologies for applying the technique. These methodologies, one for inorganic mass spectrometry and the other for organic mass spectrometry, have been developed and tested through a series of collaborative studies carried out by a sub-committee of The Royal Society of Chemistry's Analytical Methods Committee.

This book will be of assistance to anyone attempting to extract the maximum information, from any set of data, using curve fitting methods. In addition, the book shows how advanced fitting techniques such as robust fitting with splines and non-linear regression are applied to practical problems. The book also includes derivation of the statistical errors that are present in this type of analysis. It is written in a manner so that the impatient reader can rapidly get into fitting spectra.

Astrometry from space was performed for the first time and with great success by the ESA Hipparcos satellite (1989-93). This mission was designed as an as trometry mission, but the use of a photon counting detector made it possible to produce very important photometric results: the most accurate astronomical pho tometry ever by the main Hipparcos mission in a very broad band of 120000 stars, and the two-colour Tycho-2 photometry of 2.5 million stars. The cornerstone ESA mission GAIA was approved in October 2000 for launch not later than 2012. This mission will use CCDs in time-delayed...

Magnetic resonance techniques are especially interesting in the study of colloids and interfaces due to their unique ability to elucidate structure, dynamics and function at the atomic and molecular level. This book illustrates the most up to date applications of innovative NMR and EPR techniques, including magnetic resonance imaging and microscopy, to gas-solid and liquid-solid interfaces, organic and biological surfaces, microemulsions, liquid crystals, membranes, structure and dynamics of polymers and micellar systems, and diffusion in heterogeneous systems.
