We performed selective excitations of the first- and second-excited Frenkel exciton states (Q- and B-excitons) with use of sub-40-fs and sub-5-fs visible laser pulses. The transient absorption signals exhibit oscillatory features associated with molecular vibrations. From an analysis of the spectral profiles of the phase and amplitude of the oscillation, the experimental result is well explained by the modulated transition dipole moment, which is caused by the dynamic intensity borrowing from the intense B-transition to the weak Q-transition.
