| Popis: | ’We present a study of the multiplex picosecond CSRS experiments of the mixed crystals of pentacene doped in naphthalene. By this method we are able to measure vibrational decay times from different species simultaneously. The shorter decay time measured for the 1385 cm-’ mode of naphthalene while increasing the concentration of pentacene and tuning the pump frequency near the absorption transition may be interpreted by the model of impurity perturbed domains. |
