Abstract Ultrafast multidimensional infrared spectroscopy is a powerful method for resolving features of molecular structure and dynamics that are difficult or impossible to address with linear spectroscopy. Augmenting the IR pulse sequences by resonant or nonresonant UV, Vis, or NIR pulses considerably extends the range of application and creates techniques with possibilities far beyond a pure multidimensional IR experiment. These include surface‐specific 2D‐IR spectroscopy with sub‐monolayer sensitivity, ultrafast structure determination in non‐equilibrium systems, triggered exchange spectroscopy to correlate reactant and product bands, exploring the interplay of electronic and nuclear degrees of freedom, investigation of interactions between Raman‐ and IR‐active modes, imaging with chemical contrast, sub‐ensemble‐selective photochemistry, and even steering a reaction by selective IR excitation. We give an overview of useful mixed IR/non‐IR pulse sequences, discuss their differences, and illustrate their application potential.
