Webelectronic transitions (and their couplings) involving high-energy excited states whose energies can lie beyond the ionization threshold of the target chromophores. The complexity of the nonlinear response recorded in 2D electronic spectra has motivated the development of computa-tional approaches to simulate and interpret 2DUV spectra.10−13 WebUltraviolet and visible radiation interacts with matter which causes electronic transitions (promotion of electrons from the ground state to a high energy state). The ultraviolet regionfalls in the range between 190-380 nm, the visible regionfall between 380-750 nm. The following electronic transitions are possible: π-π* (pi to pi
