| Zusammenfassung |
| Utilizing a graphite substrate at temperatures between 180 and 210 K, butanol, water ice, and
graphite interactions are investigated using molecular beam techniques at maximum
pressures of 10-2 mbar. Previous work [1,2] has demonstrated that water transport is
very sensitive to the chain length of surfactant alcohols. Using a Quadrupole Mass
Spectrometer (QMS) to measure H2O, D2O, and butanol intensities, coupled with
reflected light intensity measurements we monitor the condensation, evaporation, and
structure of ice and butanol layered surfaces. These measurements are compared
with methanol measurements made using the same experimental techniques, to
examine the relationship between atmospheric ice dynamics and surface/surfactant
structure.
