Abstract
Radical cation salts of pure hydrocarbons are model systems for organic conductors. Electron spin resonance experiments in (Fluoranthene)2PF6 − are reviewed with special emphasis on the elucidation of conduction band properties. Pulsed ESR measurements allow the direct determination of the diffusion constant of the electrons. Double resonance techniques like the Overhauser shift method allow a detailed investigation of the anisotropic hyperfine interaction of the conduction electrons with protons and 13C. The Overhauser shift technique complements Knight shift experiments. The conduction band characteristics derived from these experiments are strongly influenced by the molecular orbitals.Keywords
