| The spatial distributions of individual dibenzanthanthrene electronic transition dipole moments in solid Xe was investigated at the single molecule level, with the high-resolution fluorescence spectroscopy. Samples were prepared by the co-deposition of dibenzanthanthrene/Xe vapours onto the 50 K surface. The results indicate that the orientation of planar aromatic molecules is preferentially parallel to the trapping surface. |
