We have applied the technique of second harmonic generation to the study of the solid/vapor interface of porous toluene/water ice films at low temperature. The ice samples are condensed from the vapor onto a cold support at 90 K and are typically approximately 500 micrometers thick with an internal surface area of approximately 200 m2. The ices are transparent to both the 532 nm probe laser and to the 266 nm second harmonic signal. Second harmonic light is generated from surfaces throughout the bulk of the porous sample. Significant differences in the efficiency for second harmonic generation from water and toluene enable the species specific study of annealing and adsorption in this binary system. Measurements of the coverage dependent adsorption of toluene on water ice, and the observation of a coverage dependent liquid-solid phase transition in a few monolayers of toluene adsorbed on water ice at temperatures below the bulk toluene melting temperature are presented.
