• Sommario/riassunto: This first work to be devoted entirely to this increasingly important field, the ""Textbook"" provides both an in-depth and comprehensive overview of this exciting new area.Edited by Johann Gasteiger and Thomas Engel, the book provides an introduction to the representation of molecular structures and reactions, data types and databases/data sources, search methods, methods for data analysis as well as such applications as structure elucidation, reaction simulation, synthesis planning and drug design. A ""hands-on"" approach with step-by-step tutorials and detailed descriptions of software
