Evidence for two kinds of hydrogen-bonding networks in ionic solutions by 2D infrared correlation spectroscopy

Abstract IR spectra from 4000 to 100 cm–1 were measured for four kinds of alkali chloride solutions (LiCl, NaCl, KCl, CsCl solutions) with different concentrations. Their second derivative spectra revealed two bands around 3400 and 3160 cm–1 attributed to the OH stretching mode of weakly hydrogen-bo...
