The aim of the authors of this handbook is to apply existing techniques developed for investigation of other substances to estimate the properties of organosilicons in a wide range of parameters. The computational results summarized in the book were obtained using methods based on both the principle of thermodynamic similarity and on the additive principle. Because of their unique properties, organosilicons have found wide application in different areas of science and technology, thus creating a need for the data presented here for the first time.
