    • c is the number of kinetic components included in the analysis. A contains the traces of the kinetic components and depends on model parameters as pump-probe cross-correlation, rate constants, vibrational frequencies, and damping rates. The model parameters are optimized by a non-linear least squares routine to minimize the difference between the model Y and the experiment ΔOD(t,λ).

    • Equation 2 only shows cos oscillations. Indeed, oscillations were fitted with sin(ωt) and cos(ωt) functions for each frequency with zero initial phase. The pure cosine oscillation was then reconstructed from the sumangle trigonometric relationships, and the time-zero phase of the pure cosine function can then be obtained between 0 and 2π with avoidance of the intrinsic phase uncertainty resulting from the symmetry of the cosine function.
