We present and discuss the results of a direct observation of the picosecond rangetemporal behavior of vibronic lines in the luminescence spectrum of the matrix-isolatedperylene and anthracene molecules. A novel subtractive dispersion mount of monochromatorsin conjunction with the synchroscan streak camera has been used. Fromspectrochronograms measured at different excitation wavelengths the vibrationalenergy relaxation times have been obtained. These are in the range of 20–30 ps andare most probably determined by the existence of the phonon bath of the matrix. Acomparison of the measured relaxation constants with those estimated from thesteady-state hot luminescence spectrum has been made.
