Sommario/riassunto

Volume 16Reviews In Computational ChemistryKenny B. Lipkowitz and Donald B. BoydThe focus of this book is on methods useful in molecular design. Tutorials and reviews span (1) methods for designing compound libraries for combinatorial chemistry and high throughput screening, (2) the workings of artificial neural networks and their use in chemistry, (3) force field methods for modeling materials and designing new substances, and (4) free energy perturbation methods of practical usefulness in ligand design.From Reviews of the Series""This series spans all
