摘要:
The adsorption of DCl, CCl4, CFCl3, CF2Cl2 and CF3Cl on thin D2O ice films at 110 K has been studied using reflection-absorption infrared spectroscopy (RAIRS). These compounds interact to varying degrees with the ice surface via the OD bonds dangling into the vacuum. DCl was found to dissociate ionically, evidenced by a strong band attributable to D3O+ and the absence of any absorption band for molecular DCl.
