Abstract
Temperature-dependent (2-10 K) photon echo measurements are presented for pentacene in naphthalene at high pressure (12.5 kbar) in a diamond anvil cell. A decrease in the homogeneous dephasing rate (i.e. a narr owing of the homogeneous linewidth) is observed at high pressure. In a ddition, the temperature dependence of the homogeneous dephasing rate is used to obtain the effect of pressure on the frequency and lifetime of the pseudolocal phonon associated with a pentacene impurity in a c rystalline naphthalene matrix.
