Time-resolved difference absorption spectra of J-aggregates were measured by femtosecond pump-probe spectroscopy. The induced absorption near the J-band at 20 K was assigned to the transitions from n-exciton states to ( n + 1 )-exciton states (n 2 1) . The decay time of the n( > 2)-exciton states is
The molecular dynamics of thiophene in its neat liquid and in binary solutions with carbon tetrachloride of various mole fractions has been investigated by means of optically heterodyned optical Kerr effect (OHD-OKE) experiment. An unusual increase in orientational relaxation time at the specific mo
