Molecular Biology of the Cell
Author: Molecular Geometry
Author: Alison RodgerPublisher: Butterworth-Heinemann
ISBN: 1483106039
Category : Science
Languages : en
Pages : 203
Book Description
Molecular Geometry discusses topics relevant to the arrangement of atoms. The book is comprised of seven chapters that tackle several areas of molecular geometry. Chapter 1 reviews the definition and determination of molecular geometry, while Chapter 2 discusses the unified view of stereochemistry and stereochemical changes. Chapter 3 covers the geometry of molecules of second row atoms, and Chapter 4 deals with the main group elements beyond the second row. The book also talks about the complexes of transition metals and f-block elements, and then covers the organometallic compounds and transition metal clusters. The last chapter tackles the consequences of small, local variations in geometry. The text will be of great use to chemists who primarily deal with the properties of molecules and atoms.
Chemistry 2e
Author: Paul FlowersPublisher:
ISBN: 9781947172623
Category : Chemistry
Languages : en
Pages : 0
Book Description
Chemistry 2e is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. Changes made in Chemistry 2e are described in the preface to help instructors transition to the second edition.
Structures and Conformations of Non-Rigid Molecules
Author: J. LaanePublisher: Springer Science & Business Media
ISBN: 9401120749
Category : Science
Languages : en
Pages : 640
Book Description
From the beginnings of modern chemistry, molecular structure has been a lively area of research and speculation. For more than half a century spectroscopy and other methods have been available to characterize the structures and shapes of molecules, particularly those that are rigid. However, most molecules are at least to some degree non-rigid and this non-rigidity plays an important role in such diverse areas as biological activity, energy transfer, and chemical reactivity. In addition, the large-amplitude vibrations present in non-rigid molecules give rise to unusual low-energy vibrational level patterns which have a dramatic effect on the thermodynamic properties of these systems. Only in recent years has a coherent picture of the energetics and dynamics of the conformational changes inherent in non-rigid (and semi-rigid) molecules begun to emerge. Advances have been made in a number of different experimental areas: vibrational (infrared and Raman) spectroscopy, rotational (microwave) spectroscopy, electron diffraction, and, most recently, laser techniques probing both the ground and excited electronic states. Theoretically, the proliferation of powerful computers coupled with scientific insight has allowed both empirical and ab initio methods to increase our understanding of the forces responsible for the structures and energies of non-rigid systems. The development of theory (group theoretical methods and potential energy surfaces) to understand the unique characteristics of the spectra of these floppy molecules has also been necessary to reach our present level of understanding. The thirty chapters in this volume contributed by the key speakers at the Workshop are divided over the various areas. Both vibrational and rotational spectroscopy have been effective at determining the potential energy surfaces for non-rigid molecules, often in a complementary manner. Recent laser fluorescence work has extended these types of studies to electronic excited states. Electronic diffraction methods provide radial distribution functions from which both molecular structures and compositions of conformational mixtures can be found. Ab initio calculations have progressed substantially over the past few years, and, when carried out at a sufficiently high level, can accurately reproduce (or predict ahead of time) experimental findings. Much of the controversy of the ARW related to the question of when an ab initio is reliable. Since the computer programs are readily available, many poor calculations have been carried out. However, excellent results can be obtained from computations when properly done. A similar situation exists for experimental analyses. The complexities of non-rigid molecules are many, but major strides have been taken to understand their structures and conformational processes.
Shape in Chemistry
Author: Paul G. MezeyPublisher: Wiley-VCH
ISBN: 9780471187417
Category : Science
Languages : de
Pages : 224
Book Description
'Shape in Chemistry' looks at molecular shape from a unique perspective: It introduces the reader to the topological concepts and methods of precise shape characterization that are applicable for direct, non-visual description and analysis of general molecular shapes. The author provides a pictorial introduction to all the topological tools necessary for the subjects discussed. Mathematical description is also provided at an easily comprehensible level. New concepts are introduced beginning at the familiar level of stereochemistry and lead on to more advanced topological shape analysis methods. The structure of the book reflects the author's desire to bring the reader to an early appreciation of the power of topology in chemistry. After a brief review of the quantum chemical concept, the author compares the merits of visual, computer graphics methods and nonvisual, algorithmic shape analysis methods. The book ends with the concepts of approximate symmetry and various generalizations of symmetry. 'Shape in Chemistry' is surely destined to become standard reading in the field. It presents a valuable addition to the literature on shape and modeling of molecules for non-specialists organic, physical and medical chemists, researchers in various aspects of QSAR and pharmacological drug design and advanced undergraduate and graduate students.

Beyond the Molecular Frontier
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309168392
Category : Science
Languages : en
Pages : 238
Book Description
Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.
