Abstract
A unique system has been developed and used to determine the surface tension of free-standing films of three different liquid-crystal compounds in the smectic phases. The results obtained have been found to be in good agreement with the existing experimental data. For one of these compounds, the surface tension has also been found to be independent of film thickness from over 100 down to only 2 molecular layers.Keywords
