摘要：

Stark shifts of the zero phonon line of the vibrationless S1<--S0 transition of single pentacene molecules embedded in p-terphenyl crystals have been investigated at cryogenic temperatures. The energy shifts are mainly determined by the quadratic Stark effect. The contribution of the linear Stark effect is rather small and varies strongly from molecule to molecule. The polarizability differences for the ground and first excited state have been calculated from the experimental data obtained from a detailed study of eight single molecules.
