✦ Synopsis

We observed spectral lines from single molecules in a new disordered system: terrylene in polyethylene. Different linewidths for different molecules and photoinduced frequency jumps are observed. Measurements of the Stark effect on single molecules are presented. The lines shift linearly under applied electric field, showing that the molecular symmetry is broken by interactions with the matrix. The shifts differ strongly according to the molecule. Some molecules show surprisingly strong induced dipole moments of up to 5 D, an illustration of how strong the solvent-solute interaction can be, even in non-polar systems.
