✦ Synopsis

The hydrostatic pressure-induced shift of the zero-phonon line of single pentacene molecules in a pterphenyl host crystal was studied at cryogenic temperatures. Five molecules in the inhomogeneously broadened &t-S, absorption band of the O1 site (592.32 nm) were selected. In the low-pressure regime (App6 600 hPa), all molecules showed a linear and reversible frequency shift to the red, varied from -0.74 to -1.0 MHz/hPa.

The hydrostatic-pressure shift of the zero-phonon lines of single terrylene molecules in a p-terphenyl host crystal was measured at 1.6 K. We found four inhomogeneous absorption bands of the terrylene molecules in p-terphenyl with inhomogeneous widths between 15 and 33 GHz, corresponding to four cry
