Book Description
Molecular spectroscopy has achieved rapid and significant progress in recent years, the low temperature techniques in particular having proved very useful for the study of reactive species, phase transitions, molecular clusters and crystals, superconductors and semiconductors, biochemical systems, astrophysical problems, etc. The widening range of applications has been accompanied by significant improvements in experimental methods, and low temperature molecular spectroscopy has been revealed as the best technique, in many cases, to establish the connection between experiment and theoretical calculations. This, in turn, has led to a rapidly increasing ability to predict molecular spectroscopic properties. The combination of an advanced tutorial standpoint with an emphasis on recent advances and new perspectives in both experimental and theoretical molecular spectroscopy contained in this book offers the reader insight into a wide range of techniques, particular emphasis being given to supersonic jet and matrix isolation techniques, spectroscopy in cryogenic solutions (including liquid noble gases), and in both crystalline and amorphous states. Suitable quantum chemical methods are also considered, as are empirically based force field methods for calculating spectra of large molecular systems. The wide range of topics covered includes: molecular dynamics and reactivity, time-resolved and high-resolution spectroscopy, conformational analysis, hydrogen bonding and solvent effects, structure and dynamics of weakly bound complexes, transition metal and organic photochemistry, spectroscopy of excited states, ab initio prediction of molecular spectra, and biochemical and astrophysical applications.

Book Description
The matrix isolation (MI) method has now been used for nearly thirty years. During this period it has been actively developed and the range of problems tackled greatly extended. Originally it was used for studies of transient species involv ing vibrational, electronic and ESR spectroscopy. Nowadays the study of transient species forms a comparatively small part of HI work since it has been amply demonstrated that very fruitful information can be obtained of the structure and interactions of stable molecules and their aggregates. In addition to the s~ectroscopic methods mentioned above the MI technique is nowadays a standard method in research based on vibrational relaxation, luminescence, Mossbauer, magnetic circular dichroism, pulsed NMR and photoelectron spectroscopy. The matrix isolation technique affords considerable advantages over more conventional methods in most applications of spectroscopy. Areas where the technique has been widely applied, or shows great potential, include: metal atom chemistry, and its relation to surface chemistry, high temperature inorganic species, transition metal complexes, interstellar species, free radicals and unstable molecules, conformational studies, molecular com plexes, and intermolecular forces.

Book Description
Tunneling reactions in chemistry are characterized by the low-temperature limit when the classical contribution is negligible. Many practical applications benefit from the lack of heat and have a deep physical basis. Interesting advantages of chemical synthesis at low temperatures have also been demonstrated. This book covers fundamental and practical aspects of the processes and experimental and theoretical methods used in the field. The chapters are written by leading scientists who have very strong experience in the selected topics, and many practical recommendations can be found in this book.

Book Description
This book is devoted to nanochemistry: a branch of the actively developing interdisciplinary field of nanoscience. This branch of science studies the processes to production and reactions of nanoparticles and their compounds. It has been shown that such particles are of high activity and can undergo new and unusual chemical transformations. These transformations play an active role in our daily lives to provide reagents for self-cleaning glass surfaces and fabrics, different antiseptic coverings, sensors for monitoring the environment and catalysts preventing pollution. Nanochemistry covers the main studies of these reactions and reviews the work of leading scientists from different countries around the world. This book is the first monograph on nanochemistry, combining the elements of review and text book which allows for information on current and prospective directions in nanochemistry.
