Paper Abstract

The surface sensitive laser technique second harmonic generation has been utilized to probe the adsorption of p-tolualdehyde (TA) at the ice/vacuum interface. The non-Langmurian adsorption behavior can be explained by a model in which the TA initially adsorbs as a weakly bound precursor species that is highly mobile and eventually settles to form a more strongly bound species. The relative sticking coefficient for p-tolualdehyde on the ice surface was found to be 40% smaller than that on a NaCl crystal.
