Download or read book Applications of Time resolved Optical Spectroscopy written by Volkmar Brückner and published by Elsevier Publishing Company. This book was released on 1990 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-resolved optical spectroscopy has developed rapidly in recent years, and the development of various types of lasers for ultrashort light pulses has enabled spectroscopists to increase the temporal resolution to the picosecond, and even femtosecond, range. The field of ultrafast spectroscopy, while still in its early stages, is evolving rapidly and a compilation of methods and results, their classification and critical evaluation is therefore greatly in demand. This book meets that need by summarizing and classifying current knowledge on the application of ultrafast optical methods in photophysics, photochemistry, photobiology and other related fields. Written in textbook style, it begins with a short summary and discussion of the relevant methods and devices, ranging from millisecond flash photolysis to femtosecond devices, and covering the detection of short-lived intermediates by time-resolved Raman spectroscopy. This is followed by a detailed description of data analysis and interpretation of results for various experimental methods. The authors discuss very thoroughly the precision of experimental data, the potential of data-acquisition systems and the necessity of combining various experimental methods in order to investigate complex processes. Applications are discussed from the point of view of scientists interested in the detection and investigation of (photo)reactions by means of time-resolved optical methods. The processes occurring in photophysics, photochemistry and photobiology are therefore described in connection with the information available from time-resolved optical spectra. The book is suitable both as an advanced text for students of physics and chemistry, and as a reference work for professional spectroscopists. It provides them with an introduction to the variety of processes occurring after excitation of molecules and a thorough understanding of the potentials and limitations of various ultrafast spectroscopic methods which are used to observe these processes.

Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Book excerpt: Light and light based technologies have played an important role in transforming our lives via scientific contributions spanned over thousands of years. In this book we present a vast collection of articles on various aspects of light and its applications in the contemporary world at a popular or semi-popular level. These articles are written by the world authorities in their respective fields. This is therefore a rare volume where the world experts have come together to present the developments in this most important field of science in an almost pedagogical manner. This volume covers five aspects related to light. The first presents two articles, one on the history of the nature of light, and the other on the scientific achievements of Ibn-Haitham (Alhazen), who is broadly considered the father of modern optics. These are then followed by an article on ultrafast phenomena and the invisible world. The third part includes papers on specific sources of light, the discoveries of which have revolutionized optical technologies in our lifetime. They discuss the nature and the characteristics of lasers, Solid-state lighting based on the Light Emitting Diode (LED) technology, and finally modern electron optics and its relationship to the Muslim golden age in science. The book’s fourth part discusses various applications of optics and light in today's world, including biophotonics, art, optical communication, nanotechnology, the eye as an optical instrument, remote sensing, and optics in medicine. In turn, the last part focuses on quantum optics, a modern field that grew out of the interaction of light and matter. Topics addressed include atom optics, slow, stored and stationary light, optical tests of the foundation of physics, quantum mechanical properties of light fields carrying orbital angular momentum, quantum communication, and Wave-Particle dualism in action.

Download or read book Time resolved Analytical Methods for Liquid written by and published by . This book was released on 1993 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical phenomena occurring at boundaries between insulating solids and liquids (adsorption, partition, monolayer self-assembly, catalysis, and chemical reactions) are important to energy-related analytical chemistry. These phenomena are central to chromatography, solid-phase extraction, immobilized analytical reagents, and optical sensors. Chemical interactions in these processes cannot generally be identified solely by equilibrium surface concentrations, since the steady-state behavior does not reveal the mechanism or rates of surface reactions. Goal therefore is to develop surface-sensitive spectroscopies by which chemical kinetics at liquid/solid interfaces can be observed on time-scales from nanoseconds to seconds. In the first year, we have used Joule-discharge heating kinetics to study pore structure of silica gels; effects of pore diameter, particle size, and chemical modification on pore connectivity were investigated. Temperature-jump relaxation measurements of sorption/desorption kinetics at liquid/solid interfaces were also carried out using Joule heating; kinetic barriers to sorption of ions from solution were found for both C18 and Cl surfaces. Through a collaboration with Fritz-Haber Institute in Berlin, we were able to acquire laser temperature-jump data on kinetics at liquid/solid interfaces using a colloidal sample. We also quantified the rate of migration of covalently attached ligands on silica surfaces; from the temperature dependence, the large energy barrier to migration was estimated. A review of applications of electronic spectroscopy (absorption and fluorescence) to reversed-phase chromatographic interfaces was published.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this Workshop on "Selectivity in Chemical Reactions" was to examine the specific preferences exhibited by simple chemical reactions with regards to reagents having particular energy states, symmetries, alignment and orientation and the resulting formation of certain products with their corresponding energies, states, alignment and polarisation. Such problems come close to the ultimate goal of reaction dynamics of being able to determine experimentally and theoretically state-to-state cross sections and stereochemical effects under well defined and characterised conditions. There are many examples of highly selective and specific processes to be found in atmospheric and combustion chemistry and the production of population inversions amongst vibrational and electronic states lies at the heart of the development of chemical laser systems. Only when we can understand the fundamental processes that underlie the selectivity in the formation of products in a chemical reaction and the specific requirements of initial states of the reagents, can we expect to be able to develop the explanatory and predictive tools necessary to apply the subject to the development of new laser systems, efficient combustion schemes and specific methods of chemical synthesis, to the control of atmospheric pollution and to all problems in which it is necessary to direct the outcome of a chemical reaction in a specific way. The brief given to the Workshop was to critically review the field, to discuss the present limitations and difficulties and to identify new directions.
