Brown in the Weissberger series in 1971, the second was edited by H. Durr and H. Bouas-Laurent in the Elsevier series in 1990. A third book, edited ...
Organic Photochromic and Thermochromic Compounds: Volume 2: Physicochemical Studies, Biological Applications, and Thermochromism
This publication is the fourth major treatise on photochromism involving organic molecules and derived systems. The first such book was edited by G.H. Brown in the Weissberger series in 1971, the second was edited by H. Durr and H. Bouas-Laurent in the Elsevier series in 1990. A third book, edited by C.B. McArdle, should be added to the list, which focuses on the very important topic of the behavior of photochromic systems in polymer matrices.; This book is a result of the large increase in the number of publications and patents concerning photochromic compounds and their use in various applications, such as ophthalmic lenses and security printing, during the last 10 years. As a result of this increased interest, two successful International Symposia on Photochromism have been held: the first, ISOP93, in France on Embiez Island near Bandol (September 12-16, 1993) and the second, ISOP96, in the United States in Clearwater, Florida (September 8-12, 1996). The number of countries represented at each of these symposia (17 and 16, respectively) attests to the international scope of the photochromic research community. This global interest is also exemplified by the authors of the chapters within this book. The aim of the second volume of this new review is focused on the physico-chemical properties and photochromic behavior of the best-known systems, leading to new developments in the known photochromic series or the discovery of new families.; However, chapters are included on the most appropriate physico-chemical methods by which photochromic substances can be studied (spectrokinetic studies on photostationary states, Raman spectroscopy, EPR, chemical computations and molecular modeling, X-ray diffraction analysis). In addition, special topics such as interaction between photochromic compounds and polymer matrices, photodegradation mechanisms, and potential biological applications have been treated. The last chapter, on thermochromic materials, is included to emphasize the chemical similarities between photochromic and thermochromic materials.; In general, the literature cited within the chapters covers publications through 1995.

Biological Magnetic Resonance: Volume 19: Distance Measurements in Biological Systems by Epr: 19
The foundation for understanding the function and dynamics of biological systems is knowledge of their structure. Many experimental methodologies are used for determination of structure, each with special utilities. The volumes in this series on Biological Magnetic Resonance emphasize the methods that involve magnetic resonance. This volume seeks to provide a critical evaluation of EPR methods for determining the distances between two unpaired electrons. The editors invited the authors to make this a very practical book, with specific numerical examples of how experimental data are worked up to produce a distance estimate, and realistic assessments of uncertainties and of the range of applicability, along with examples of the power of the technique to answer biological problems.

Chemometrics: from Basics to Wavelet Transform
Wavelet Transformations and Their Applications in Chemistry pioneers a new approach to classifying existing chemometric techniques for data analysis in one and two dimensions, using a practical applications approach to illustrating chemical examples and problems. Written in a simple, balanced, applications-based style, the book is geared to both theorists and non-mathematicians.This text emphasizes practical applications in chemistry. It employs straightforward language and examples to show the power of wavelet transforms without overwhelming mathematics, reviews other methods, and compares wavelets with other techniques that provide similar capabilities. It uses examples illustrated in MATLAB codes to assist chemists in developing applications, and includes access to a supplementary Web site providing code and data sets for work examples. Wavelet Transformations and Their Applications in Chemistry will prove essential to professionals and students working in analytical chemistry and process chemistry, as well as physical chemistry, spectroscopy, and statistics.

Quality Control Advisor and GC Advisor
The Quality Control Advisor and GC Advisor provides answers, explanations, and definitions for selecting the QC samples and GC detectors needed to meet your specific data quality objectives. It takes the guesswork out of these critical aspects of sampling and analysis. The program covers quality control samples such as instrument blanks, solvent blanks, laboratory blank spikes, field blank spikes, QC check samples, trip blanks, equipment blanks, material blanks, background samples, area control samples, duplicate samples, replicate samples, and replicate analyses. The program will help you save time and money by eliminating QC samples not needed and by making sure you don't forget the QC samples needed for your specific objectives. If you already have analytical data, you can input the QC samples you have and the program will advise what kinds of QC data quality objectives they can be used for, as well as indicate the type of QC information for which they cannot be used. GC detectors include mass spectrometers (full scan and selected ion monitoring), electron capture, electrolytic conductivity, nitrogen/phosphorous, flame photometric, flame ionization, and photoionization. The advantages and disadvantages of each are presented along with recommendations for which detectors to use based on confidence level, sensitivity, selectivity, and pollutant types. This program is based on the ACS Principles of Environmental Sampling, ACS Principles of Environmental Analysis, L.H. Keith's Environmental Sampling and Analysis-A Practical Guide, and J. K. Taylor's Quality Assurance of Chemical Measurements. They are essential for anyone who plans or participates in sampling and analytical activities or uses data from environmental analytical laboratories.

Handbook of Cyanobacterial Monitoring and Cyanotoxin Analysis
This timely book focuses on the monitoring, analysis and assessment of mass populations of cyanobacteria (bluegreen algae) in natural and controlled waters, including lakes, rivers and drinking water reservoirs which are being increasingly affected by cyanobacterial mass populations (blooms) at global level. This handbook features a comprehensive range of up-to-date review chapters, followed by a corresponding series practical methods in a major and growing field of environmental, microbiological and ecotoxicological monitoring and analysis. The practical chapters, termed Standard Operating Procedures (SOPs), have undergone rigorous inter-laboratory trial and validation, and are presented in sufficient detail to enable a wide range of end-users to follow the procedures in the laboratory, in academic and government institutions and in industrial settings, including water treatment plants.The instroductory and review chapters will provide up-to-date overviews plus the necessary foundation for the subsequent use of the practical chapters for monitoring, analysis and the interpretation of the results. The practical chapters will contain the necessary details to enable operators to perform the monitoring and analytical procedures in the field and laboratory.This timely book focuses on the monitoring, analysis and assessment of mass populations of cyanobacteria (bluegreen algae) in natural and controlled waters, including lakes, rivers and drinking water reservoirs which are being increasingly affected by cyanobacterial mass populations (blooms) at global level.
