TEMPERATURE DEPENDENCE OF THE SHAPE OF THE ROTATION-VIBRATION FUNDAMENTAL OF HCl IN SOLUTION

Abstract

Author Institution: D\'epartment de Chimie, Universit\'e Laval, Qu\'ebec; Centre des Recherches sur les Atomes et Les Mol\'ecules, Universit\'e Laval, Qu\'ebecMoment analyses have been made of the rotation-vibration fundamental of HCl dissolved in a number of nonpolar solvents. The second moment of the band is found to vary linearly with temperature in agreement with Gordon’s theory. The fourth moment, which is a function of the torque acting on the solute molecule due to solute-solvent interaction, exhibits a more complex temperature dependence. The results will be interpreted using a simple model."
