The structure and dynamics of monomolecular adsorbed layers of long‐chain 1‐alkanols can be made visible by electron scanning tunneling microscopy. The packing in single domains and the pattern at the domain boundaries (shown here for 1‐octadecanol) confirm the crucial role of the hydroxy groups in the packing of molecules; the common structures at the domain boundaries suggest that all potential hydrogen bonds are indeed formed. The reorganization of regions containing many defects and the incorporation into the domain structure of impurities are also observed.
