The electronic structure of pentacene deposited on a Au(111) substrate in the initial stage of growth was investigated using metastable deexcitation spectroscopy. The occupation of the pentacene π[sup *] 4b[sub 1u] orbital, which corresponds to the lowest unoccupied molecular orbital of the gas phase species, was found at the Fermi level. The donation and backdonation-type interactions between the pentacene adsorbate and the Au surface are discussed. © 2003 American Institute of Physics.
