Abstract
The infrared absorption spectra of the crystalline methoxides of lithium, sodium and potassium and their deuterated derivatives, as well as the ethoxides of lithium and sodium, have been measured in the 2–25μm region and interpreted. It has been shown that the successive displacement of the C-H (C-D) stretching frequencies to the longwave region, on passing from methanol to the methoxides of lithium, sodium and potassium, is determined by the differences in the nature of the O-H, O-Li, O-Na, and O-K bonds. The stretching frequency displacement effect and the structure of the compounds are discussed.
