The kinetics and dynamics of chlorodifluoromethane (CHF2Cl) adsorption on and desorption from 30-bilayer-thick amorphous solid water (ASW) and crystalline ice (CI) films were studied utilizing molecular beam techniques and thermal desorption spectroscopy. The adsorbed state and desorption kinetics of CHF2Cl are sensitive to the surface structure and, hence, the degree of crystallinity of ice. Chlorodifluoromethane binds more strongly to Cl than ASW and desorbs at a higher temperature during thermal desorption spectroscopy (TDS), altering the spectrum line shape and allowing differentiation between the two phases. Adsorbed states and thus the TDS line shape also respond to structural changes on the ASW surface prior to the onset of crystallization. The value of the condensation coefficient (a), a measure of CHF2Cl adsorption kinetics and dynamics, is high on both surfaces (similar to 1). However, a small but reproducible variation of a with the phase of solid water can be used to distinguish ASW from Cl. The sensitivity of CHF2Cl adsorption and desorption to ice surface structure can contribute information about the phase and morphology of bulk ice, provided that the structure of the surface reflects that of the bulk.
