Abstract
The structures of anthracene adlayers on Ag(111), Ag(100), and Ag(110) elec trode surfaces in dilute perchloric acid have been investigated in detail b y using in situ scanning tunneling microscopy (STM). Anthracene was found t o form highly ordered molecular layers with a flat-lying orientation on the Ag single-crystal electrode surfaces in the double-layer region. High-reso lution STM images allowed us to reveal packing arrangements of anthracene. Highly ordered anthracene adlayers with (2 root3 x 2 root3)R30 degrees (the ta = 0.08), c(4 x 6) (theta = 0.08), and c(4 x 4) (theta = 0.125) symmetrie s were observed on Ag(111), Ag(100), and Ag(110) surfaces, respectively.
