Understanding Single-Crystal X-Ray Crystallography

Endlich ein Lehrbuch der Röntgenkristallstrukturanalyse von Einkristallen, das ohne weitreichende Vorkenntnisse in Mathematik auskommt! Theorie und methodische Grundlagen werden logisch strukturiert und gut verständlich dargestellt; der Band ist in sich geschlossen und erfordert keine Zusatzliteratur. Für Studenten oberer Semester, Diplomanden und Doktoranden sowie zum Einstieg für Anwender aus allen naturwissenschaftlichen Disziplinen.

Professor Dennis W. Bennett is a Professor of Chemistry and a member of the Laboratory for the Surface Studies at University of Wisconsin in Milwaukee. His research focuses on the physical-inorganic chemistry of molecular devices and catalytic systems. He holds a BS in Biological Sciences and a PhD in Chemistry, both from the University of Utah, where he also did post-doctoral research in photocatalysis. In more recent years, he was a NIH Senior Fellow at the Medical College of Wisconsin, where he gained expertise in macromolecular crystallography. He has also served as Chair of the Department of Chemistry and Biochemistry at UWM, and as a program manager in Basic Energy Services at the U.S. Department of Energy. Prior to his academic career, he was a research chemist at Phillips Petroleum Corp., and has continued to serve as a consultant to a number of companies and government agencies throughout the U.S. He is the author of over 130 peer-reviewed research publications.

X-ray crystallography is a powerful and widely used method for studying molecular structures. Small crystals of the molecule are created and these are then investigated using an X-ray beam. The crystal scatters the X-rays in a characteristic pattern, which can be analyzed to reveal the exact structure of the molecule. This is the first textbook which examines and explains this method to users with only modest mathematical backgrounds and presents the theory and fundamentals in an easily comprehensible, self-contained way. The result is a must-have for advanced undergraduate students, graduate students, and professional users of single-crystal X-ray crystallography from many various disciplines. In order to aid with learning and understanding, exercises and solutions related to X-ray crystallography can be found on our website: www.wiley-vch.de/publish/en/books/ISBN978-3527-32794-2
