Scanning tunneling microscopy and near-edge X-ray-absorption fine structure observations show that CoII tetraphenylporphyrin molecules adsorbed on Cu(111) adopt a distorted saddle-shaped geometry. Scanning tunneling spectroscopy allowed the shape and symmetry of single frontier molecular orbitals to be identified and correlated with the intramolecular structure of the porphyrin (see picture).
