A nanoscale probe of ice morphology

Article Abstract:

The results of kinetic measurements of CCl4 desorption from amorphous D2O ice films prepared under varying conditions are presented. It was established that at submonolayer coverages CCl4 desorption from D2O ice films depends heavily on the ice preparation conditions.

Variation of desorption kinetics with ice preparation conditions and evidence for distinct structures of low-density amorphous ice

Article Abstract:

Research into the desorption kinetics of CCl4 from thin amorphous D2O ice films is presented. It was established that, depending on the deposition rate and temperature, D2O molecules at the ice surface can be present in states which are mainly two-, three- or four-coordinated.

Interaction of Hydrogen Chloride with Thin Ice Films: the Effect of Ice Morphology and Evidence for Unique surface species on Crystalline Vapor-Deposited ice

Article Abstract:

A single Temperature programmed desorption mass spectrometry (TDPDMS) designated as beta-HCL, is experimented with ice films vapor deposited at substrate temperatures below 153 K and with ice films prepared by annealing of amorphous ice at 170-180 K. The morphologies of annealed and vapor deposited films and their effects on interactions of hydrogen chloride with ice are discussed.
