examination of intramolecularhydrogenbonding in the trisiloxane-1,5-diols has provided useful data on the stereochemistry of these compounds. Valencydeviation due to the gem-diphenyl groups has been proposed to explain the high intramolecular hydroxy-frequency shift of hexaphenyltrisiloxane-1,5-diol relative to those given by the other trisiloxane-1,5-diols. A second intramolecular band given by
