Pseudocolor representation fs-TA spectra of a 1D and d 2D systems. Beating maps of oscillatory components after subtracting the exponential decay: b 1D system; e 2D system. Probe wavelength resolved vibrational frequencies of c 1D and f 2D systems directly obtained by Fourier transforming the differential TA spectrum. g Slices of Fourier transformed beating maps at dominant mode frequencies. Vibrational spectra with the Lorentzian fitting results: h 1D system (probed at 850 ± 25 nm); i 2D system (probed at 550 ± 25 nm). V and M are used to distinguish the modes in these two systems.
