We report ultrabroadband two-dimensional electronic spectroscopy (2D ES) measurements obtained in the pump–probe geometry using conventional optics. A phase-stabilized Michelson interferometer provides the pump-pulse delay interval, τ1, necessary to obtain the excitation-frequency dimension. Spectral resolution of the probe beam provides the detection-frequency dimension, ω3.

Molecular (dye) aggregates are of interest in a number of fields including natural and artificial light harvesting, (1−5) organic optoelectronics, (6−8) and nanoscale computing. (9−16) An essential element in each of these fields is the process of energy transfer. In natural light harvesting, for example, electronic energy is usually transported with high quantum efficiency from the antennae to the reaction centers, where charge separation occurs to drive the energy-storing chemical reaction.
