Abstract
Individual pentacene-d(14) molecules doped into a p-terphenyl-d(14) ho st crystal have been studied by optically detected electron paramagnet ic resonance spectroscopy. The magnetic resonance transitions between the triplet sublevels of the pentacene molecule and the splitting of t he resonance lines for a molecule that contains a carbon-13 nucleus ha ve been observed in an edernal magnetic field. This splitting is cause d by the hyperfine interaction of the triplet electron spin with the s ingle carbon-13 nuclear spin.
