Reviews in Computational Chemistry. V. 18

Автор(ы):Lipkowitz K. B., Boyd D. B.
Год изд.:2002
Описание: Topics in a number of important areas of computational chemistry are the substance of this volume. Chapter 1 of this volume is a tutorial on clustering methods. Chapter 2 summarizes what has been learned about scoring functions and gives an example of how they have been applied to find new ligands in databases of real and/or conceivable (virtual) molecular structures stored on computers. In Chapter 3, Professors Steven W. Rick and Steven J. Stuart scrutinize the methods that have been devised to account for polarization. In Chapter 4, Professors Dmitry V. Matyushov and Gregory A. Voth present a rigorous frontier report on the theory and computational methodologies for describing charge-transfer and electron-transfer reactions that can take place in condensed phases. In Chapter 5, Dr. George R. Famini and Professor Leland Y. Wilson teach about linear free energy relationships (LFERs) using molecular descriptors derived from—or adjuncts to—quantum chemical calculations. In Chapter 6, Professor Dr. Sigrid D. Peyerimhoff masterfully traces the history of computational chemistry in Germany. This chapter complements the historical accounts covering the United States, Britain, France, and Canada, which were covered in prior volumes of this book series. Finally, as a bonus with this volume, editors present a perspective on the employment situation for computational chemists. The essay in the appendix reviews the history of the job market, uncovers factors that have affected it positively or negatively, and discusses the current situation.
