摘要: Small organic molecules on ice and water surfaces are ubiquitous in nature play a crucial role many environmentally relevant processes. Herein, we combine surface-specific vibrational spectroscopy controllable flow cell apparatus to investigate the molecular adsorption of acetone onto basal plane single-crystalline hexagonal with large surface area. By comparing ice/air water/air interface, observed two different types adsorption, as apparent from responses both free O-H hydrogen-bonded network vibrations for liquid water. Adsorption occurs preferentially through interactions OH group, while interaction appears less specific.
