Effect of non-Condon effect on transient absorption signals of indocyanine green molecule has been obtained using femtosecond transient absorption spectroscopy. Practicability of observation is, nevertheless, widespread; it is unfeasible to pinpoint the origin of observed oscillation in transient absorption or time-resolved fluorescence. When the oscillation are analyzed, it has been customary to apply the Condon approximation, that is, transition dipole moment change induced by molecular vibrational motion has been neglected. Consequently, a method of elucidation on the origin of observed intensity modulations deserves consideration. The method would be actualize through measuring the initial phase difference of the oscillations observed at the blue and red side wavelength of spectral band.
