Multi-dimensional optical or vibrational spectroscopy is a special class of time domain nonlinear optical spectroscopy that employs multiple ultra-fast laser pulses to obtain information about the couplings between quantum states in a variety of molecular or condensed matter systems. Since these couplings are often sensitive to the detailed structural configuration of the active molecules and the overall dynamical system evolution including interactions with the local environment, a great deal of information can potentially be obtained. It is especially well suited to follow the evolution of quantum coherences in light initiated reactions, including photosynthesis, or as an exceptionally useful probe of protein dynamics in solution. In fact, as demonstrated over the years, a vast number of different experimental configurations are possible depending on the chosen pulse sequences, geometric arrangement and polarization and signal detection method. Hopefully, this talk imparts a sound conceptual basis that will enable the diligent researchers to understand the importance of this extensive and rapidly growing research field.
