Popis:	To explain the experimental observation that a short pulse with energy exceeding a threshold can induce the outward solute migration in an ethanolic solution of chloroaluminum phthalocyanine, we have modeled each solute molecule as an oscillator confined within a potential well formed by the attractive forces of neighboring solvent molecules. In this report, we further infer that the threshold increases with a decreasing solution temperature. This inference is verified by measuring the energy thresholds for a 19 picosecond pulse to induce the outward solute migration in this solution at two temperatures of 288 K and 293 K.
