Many molecular arrangements have been successfully revealed, such as liquid crystal \cite{Sheng_dodecanthiol1,Sheng_dodecanthiol2}, n-alkanes \cite{Sheng_dodecanthiol3,Sheng_dodecanthiol4}, alkoxylated molecules \cite{Sheng_dodecanthiol5}, alkanols and alkanethiols \cite{Sheng_dodecanthiol6}. Data obtained from STM images can help to understand the relative importance of molecule and molecule, and molecule and substrate interaction as well as the types of forces responsible for a particular packing order on the surface. On the other hand, adsorption of alkanethiols onto graphite provides a good model system for the study of molecular adsorption and the structure of the adsorbed layer. Previous experiments \cite{Sheng_dodecanthiol3-7} have suggested that the molecules are adsorbed with their long-axis parallel to the graphite surface. The results have been con゙rmed in STM studies of hydrocarbons on graphite, which reveals that the molecules lie on the graphite surface and exhibit a high degree of order. Molecular-resolution images of 1-dodecanethiol (Fig.\ref{Sheng_dodecanthiol/Figure1}) on the graphite substrate are successfully observed with a scanning tunneling microscope in air(Fig.\ref{Sheng_dodecanthiol/Figure2}). The image reveals a two-dimensional ordering with the molecules lying down and arranged in rows on the graphite surface(Fig.\ref{Sheng_dodecanthiol/Figure3}). A 5.5 nm periodicity observed suggests that there are three molecules arranged in series along the molecular axis. Two kinds of molecular arrangements exist within a single row, with one subrow about 1.5 nm wide with one 1-dodecanethiol and the other subrow about 3.5 nm in width approximately double the length of the molecule. The periodicity vertical to the molecular axis is about 0.55 nm, comparable with the Van der Waals diameter of the molecule. A model (Fig.\ref{Sheng_dodecanthiol/Figure4})for the possible arrangement of the molecules on graphite surface is proposed. \begin{figure}[htbp] \centering \includegraphics[width=.5\textwidth] {./Figures_molecule/Sheng_dodecanthiol/Figure1.eps} \caption{ Chemical structure of the 1-dodecanethiol. } \label{Sheng_dodecanthiol/Figure1} \end{figure} \begin{figure}[htbp] \centering \includegraphics[width=.2\textwidth] {./Figures_molecule/Sheng_dodecanthiol/Figure2.eps} \caption{ A 32]32 nm.
