Contribution to the So-called structure temperature of the electrolyte solutions in methanol based on IR OH band-intensities

Abstract

The averaged structure temperature T str, as T with similar H-bond structure as the pure liquid, is determined of alcoholic 2.2 m solutions (anions) by IR fundamental integrated intensities. As ion series is got T str: NaClO 4, LiClO 4, LiCl, CsCl, CsF as similar Hofmeister ion series as in water. This method agrees qualitatively with the T str estimations by overtone absorbances and band analysis of non H-bonded OH. Studies of the concentration dependences of T str allows indications on water in the first hydration shell and establish the T str solution studies as useful tool for an average description of solution properties.
