Supplementary Materials

The Supplementary Material includes the following: MIIPS SHG-FROG spectrogram and interferometric autocorrelation signals; residual phase spectra of the pump and probe excitation pulses; 2DES spectra of methylene blue in water and of water blanks; variable temperature survey of the linear absorption spectrum of NpF2164g5; MBO model parameters for the absorption and fluorescence spectra at 80 K and 298 K; EADS spectrum for a 1D global model of the 2DES spectrum; 3DES FT vibronic spectrum; LPSVD model parameters for the modulated transients sampled from the 2DES spectrum and from the FM transient.
