Viologens are salts of 4,4'-bipyridine and are used in such fields as herbicides, electrochromism, solar energy conversion, molecular electronics and supramolecular chemistry. The Viologens is a comprehensive overview of the nature and physicochemical properties of the viologens and details the science behind the applications. Following a broad, discursive and self contained introduction to viologen chemistry, subsequent chapters develop the theory and present a detailed review of the most important properties and concepts in this field. A chapter on viologen synthesis is also included. This book is aimed at researchers in physical and organic chemistry, physics, materials science, biology and environmental engineering.

This thoroughy updated open-learning book provides an introduction to electroanalytical chemistry, one of today's fastest growing and most exciting branches of analytical science. This text discusses electroanalysis in a non-mathematical and informal tutorial style. In addition to over 250 discussion and self-assessment questions, 50 worked examples are also included throughout the book, thus providing a wide range of excellent material for testing the reader's understanding of the subject matter.
The topics covered include the following:

• Simple emf measurements with cells
• Equilibrium and dynamic measurements
• Polarography
• Cyclic voltammetry
• Rotated disc, ring-disc and wall-jet electrodes
• In situ spectroelectrochemistry measurements
• Impedance analysis
• Preparation of electrodes
• Data processing

The book also contains a comprehensive bibliography and details of web-based resources.
Electroanalytical Chemistry assumes no prior knowledge of this powerful branch of analytical science and will be an invaluable aid for anyone wanting to perform analytical measurements using electrochemical techniques. The book's approach is ideal for students studying at Foundation, BTEC (HNC and HND), and for those pursuing BSc and MChem courses in analytical and physical chemistry, as well as subsidiary courses in life, environmental and materials science.
Analytical Techniques in the Sciences
This series of books provides coverage of all the major analytical techniques and their application in the most important areas of physical, life and materials sciences. Each text is presented in an open-learning/distance-learning style, in which the learning objectives are clearly identified. The reader's understanding of the materials is constantly evaluated by the use of self-assessment and discussion questions.
