✦ Synopsis

The frequency of the SiH stretching absorption varies with the other substituents on the .silicon in a manner which roughly parallels the sum of their electronegativities. Using a few selected compounds as standards, one can derive a characteristic constant for each substituent group such that the SiH frequency of other substituted silanes and siloxanes can be predicted to an accuracy of *2 cm-l. The relationship of these constants to the Gordy electronegativities, and their use in characterizing silanes of umlmown structure are discussed.

The integrated molecular transform, FT,, is a unitary structure index that has been successfully used for the correlation of two-and three-dimensional structure representations with their physicochemical and pharmacological properties; it has also been shown to be a unique conformational descriptor.
