Significance Observation of cross-peaks is one of the hallmark advantages of multidimensional spectroscopy. Often times, cross-peaks overlap with strong diagonal peak features, obfuscating information that is useful for determining molecular structure. Here, we present a polarization scheme that eliminates diagonal peaks, revealing the weaker cross-peak features. This polarization scheme can be applied to one-dimensional transient absorption spectroscopy. As a result, transient absorption spectroscopy can now access information that previously required two-dimensional spectroscopies.
