(a) Absorption coefficient changes with time at selected energy points. (b) Reconstructed original spectrum of two potentials and energy points selected. (c) The exponential fitting of the time response of the coordination coefficient with a square-wave excitation at different energy. (d) The PSD analysis of the phase lag induced by the relaxation of the system. (e, f) Comparison of the corrected and uncorrected PSD demodulated spectrum and the classical difference spectrum. |
