Abstract

Thin graphite specimens, processed in electrolysis cell have been investigated by optical and electron microscopy and Raman-spectroscopy. The Raman spectra show in specimens hydrogenated the essential contribution of graphan related peak, which decreased by heating at 400oC . Computer simulation and quantum-mechanical calculation (MO LCAO) were used for estimation some structural and electronic properties.
