Abstract
X-ray diffraction illustrates that a two-dimensional smectic liquid crystal is formed in a melting process of an anisotropic, incommensurate monolayer of n-propanol physisorbed on graphite. In this phase a hydrogen-bonded head-to-head association of molecules is arranged in rows with their long axes on average normal to the row. Parallel to the rows there is only short-range translational order of the molecules.Keywords
