摘要：

STM images of organic insulating molecules adsorbed on conducting substrates can only be understood if their electronic origin is known. Images of normal alkanes on graphite (n-C36H74 is shown in the Figure) are interpreted here on the basis of their partial electron density plots rho(r0,e(f)), demonstrating that the linear alkanes can ''tumble'' and change their orientation with respect to the graphite surface.
