This thesis examines various aspects of excess excitation energy dissipation via dynamic changes in molecular structure, vibrational modes and solvation. The computational work is carefully described and the results are compared to experimental data obtained using femtosecond spectroscopy and x-ray scattering. The level of agreement between theory and experiment is impressive and provides both a convincing validation of the method and significant new insights into the chemical dynamics and molecular determinants of the experimental data. Hence, the method presented in the thesis has the...

This volume builds on the previous two editions, Environmental Photochemistry Part I and Part II, which reflect the diverse range of activities in this highly dynamic research field. The chapters cover fundamental topics, from photocatalyst materials, surface-modified materials, reaction kinetics and reactor modelling, to translational research activities on chemical synthesis, energy conversion and water treatment. The applications of the new generation of LED irradiation sources and spectroscopic methods for elucidating reaction pathways are also covered in detail....

UV-Visible Spectrophotometry of Water and Wastewater, Second Edition, represents an update to the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples, the book illustrates how this technique can be a source of new methods of characterization and measurement.

Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (e.g., Nitrate, TOC) and simultaneously qualitative information on...

Sample Introduction Systems in ICP-MS and ICP-OES provides an in-depth analysis of sample introduction strategies, including flow injection analysis and less common techniques, such as arc/spark ablation and direct sample insertion. The book critically evaluates what has been accomplished so far and what could be done to extend the capabilities of the technique for analysis of any type of sample, such as aqueous, gaseous or solid. The latest progress made in fields, such as FIA, ETV, LC-ICP-MS, and CE-ICP-MS is included and critically discussed. The book addresses problems related...

-Organic Trace Analysis- presents the basics of trace analysis, from sample preparation to the measurement: Students are introduced to statistical evaluation, quality control technologies, sampling and preparation of organic traces, as well as to enrichment and separation of samples. Spectroscopic techniques as chromatography, capillary electrophoresis, mass spectrometry, and receptor-based bioanalysis are presented in detail.

The book gives an overview on all relevant electrochemical and spectroscopic methods used in corrosion research. In addition to helping the reader choose the accurate method for a particular corrosion aspect, the various methods are correlated with industrial test methods for both the corrosion on metals (steel, zinc coated steel and aluminum) and the corrosion on coated metals (organic coatings and pre-treatments).
