This book is a comprehensive survey of currently available models, assembled, kit, and homemade. In addition to the usual crystal and molecular models, atomic and molecular orbital and macromolecular models are covered. There is also a chapter on construction devices and techniques. The descriptions of individual models include the theoretical basis of the model, materials of construction, ease of assembly, areas of application, relative cost, and more. With coverage of this scope, the individual descriptions are necessarily brief, but numerous literature references supplement the material in the book.A useful feature is an appendix listing 70 manufacturers and distributers of models, kits, and construction materials, most located in the United States and England.

High pressure spectroscopy of Kapton® polyimide film revealed a pressure-induced red shift of the absorption band edge in the visible. This shift was interpreted through application of Mulliken charge transfer complex theory and suggests that the low energy transition in polyimides is the result of an intermolecular charge transfer complex.
