Mark Ladd – författare

This book provides a study in Bonding, Structure and Solid State Chemistry. It is based on lecture courses given over several years, but is not directed at any particular degree course. Thus, it will find a place in all years of first-degree courses in both chemistry and those subjects for which chemistry forms a significant part. It will also prepare readers for more intensive study in the title topics. Pre-knowledge is assumed in mathematics and physical sciences at about A-level. Additional mathematical and other topics are presented where necessary as appendices, so as not to disturb the flow of the main text. The book is copiously illustrated, including many stereoscopic diagrams (with practical advice on correct viewing) and colour illustrations. A suite of computer programs, some of which are interactive, has been devised for the book and is available on-line from the publisher's website [insert URL here]. They are available for both 32- and 64-bit operating systems, and are easily executed on a PC or laptop; notes on their applications are provided. Problems have been devised for each chapter and fully worked 'tutorial'; solutions are included. After an introductory chapter, the book presents a study based on the main interactive forces responsible for cohesion in the solid state of matter. No classification is without some ambiguity, but that chosen allows for a structured discussion over a wide range of compounds. Each chapter includes worked examples on the study topics which, together with the problems provided, should ensure a thorough understanding of the textual material.

This book provides a comprehensive study of the symmetry and geometry of crystals and molecules, starting from first principles. The pre-knowledge assumed is mathematics and physical science to about A-level; additional mathematical topics are discussed in appendices. It is copiously illustrated, including many stereoviews, with instructions both for stereoviewing and for constructing a stereoviewer. Problems for each chapter are provided, with fully worked tutorial solutions. A suite of associated computer programs has been devised and placed on-line, for assisting both the study of the text and the solutions of the problems. The programs are easily executed, and instructions are provided in the text and on the monitor screen. The applicability of symmetry in everyday life as well as in science is stressed. Point groups and space groups are first discussed and derived in a semi-analytical manner, and later by use of group theory. The basic principles of group theory are discussed, together with applications to symmetry, chemical bonding and aspects of vibrations of molecules and crystals. The book is addressed to those studying the physical sciences and meeting the subject for the first time, and it brings the reader to a level of appreciation for the definitive works produced by the International Union of Crystallography, such as the International Tables for X-ray Crystallography, Vol 1 (1965) and the International Tables for Crystallography, Vol A (2006).

The third edition of this text has been completely rewritten and revised. It is intended for first- and second-year undergraduates in chemistry taking physical chemistry courses, and for undergraduates in other science and engineering subjects that require an understanding of chemistry. The author gives more attention to the solid and liquid states than is found in other texts on this subject, and introduces topics such as computer simulation and quasicrystals. Each chapter concludes with a set of problems, to which there are solution notes, designed to lead the reader to familiarity with the subject and its application in new situations. Computer programs designed to assist the reader are downloadable from the World Wide Web, from the time of publication. Detailed solutions to the problems will also be available via the World Wide Web. See http://www.cup.cam.ac.uk/stm/laddsolutions.htm. This modern text on physical chemistry will be of interest to undergraduate students in chemistry and also students in other areas of science and engineering requiring a familiarity with the subject.

The advances in and applications of x-ray and neutron crystallography form the essence of this new edition of this classic textbook, while maintaining the overall plan of the book that has been well received in the academic community since the first edition in 1977.

"To summarise, Professor Ladd has written a highly engaging text designed to provide the underlying principles of crystal structure determination through X-ray diffraction data. This text would be most appropriate for an early stage postgraduate or researcher interested in learning both the underlying principles of crystallography and gaining some practice with structure-solving software."Contemporary PhysicsDesigned for those who wish to understand and engage with the principles behind the process of crystal structure determination by X-ray diffraction, this title contains a comprehensive series of chapters, each of which concludes with a set of problems, for which solutions are provided. An ideal resource for senior undergraduates and early-stage postgraduates, The Essence of Crystallography has an accompanying website with programs written for the text, including an interactive simulation of crystal structure determination using prepared intensity data sets.
