Normalized transient absorption measurements for the pure P3HT polymer at probing wavelengths 500, 550, 600, and 700 nm. The inset shows the short scale dynamic behavior. The arrow indicates the time where the signal becomes positive for probing wavelength of 500 nm. The solid black line represents the mirror image of transient absorption signal with probing wavelength of 700 nm for comparison purposes
