An understanding of chemical reactivity begins with an understanding of the dynamics involved regarding system–bath interactions. Spectroscopic studies of these interactions in condensed‐phase multichromophoric systems are intricate and contain much information. Photon‐echo spectroscopy has proven to be a useful tool for probing these interactions. A description of three‐pulse photon‐echo peak shift spectroscopy (3PEPS)—theory, experiment, and application—for the study of solvation and dynamics of nanoscale excitons is presented. Also, we discuss how two‐dimensional photon‐echo spectroscopy (2DPE) relates to 3PEPS and show how 3PEPS data can be extracted from 2D photon‐echo data.
