Infrared Absorption Associated with Strong Hydrogen Bonds

Abstract

Several investigators have proposed that there exists a more or less unique relation between the O-O distance in O-H-O hydrogen bonds and the shift of O-H vibrational frequency. [1-5] However, the meager intensities of some bands which have been ascribed to this vibration (notably in nickel dimethyl-glyoxime and potassium dihydrogen phosphate) have made us a little skeptical of the correlation inthe case of very short, and possibly symmetrical, hydrogen bonds
