Scanning tunnelling microscopy (STM) has been performed in air at room temperature on bilayers
of the nucleic acid base adenine, adsorbed to a graphite surface following evaporation of saturated
aqueous solutions. Our results indicate that the upper layer of the bilayer structure shows a struc-
tural change compared to the layer adsorbed directly to the graphite. The upper layer has a
slightly larger unit cell, and is slightly sheared and rotated with respect to the layer directly ad-
sorbed to the substrate. We can interpret these observations in terms of a model of rows of the
adsorbate molecules stabilised by intermolecular hydrogen bonds.
1. Introduction
The application of scanning tunnelling microscopy (STM) [1] has proven particularly
well suited to study the molecular arrangement of close-packed adsorbate structures
physisorbed on the surfaces of inert layered compounds such as graphite. Relevant ex-
amples include cyclic aromatic compounds [1], long chain alkane derivatives [2] and
cyanobiphenyl liquid crystal derivatives [3, 4]. The physisorption of the purine base
adenine (6-aminopurine) onto solid surfaces has first
