Extended Data Fig. 2: Global and target model for the integral of the 15150–15500 cm−1 (645–660-nm) region of the excitation axis of the 2DES spectrum.

a, Four-compartment kinetic scheme, with the initial fractional excitations (in each box) and time constants. b, Time evolution of the populations. c, Evolution-associated difference spectra (EADS). d, Amplitude transients at five detection wavelengths, with the fitted global model (black curve) superimposed; the confidence intervals for each data point are indicated by bars. The T axis used in b and d is semilogarithmic, with the linear–log split at 100 fs. In d, the instrument-response function is shown for the 640-nm transient as a 12-fs Gaussian (gray dotted curve) centered at T = 0 fs.
