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
