Spectroscopy uses the interaction of light and matter to measure chemical energies. Multidimensional spectroscopy (MDS) capitalizes on nonlinearities in this interaction to peer into higher-order properties of the chemical system. These higher-order signals reveal coupling parameters of the system. In this way, scientists can use MDS to isolate unique properties of chemical systems that cannot be measured through other means. Ultrafast dynamics can also be tracked.
This presentation will introduce the basic concepts of MDS. An intuitive description of the technique will be presented. Practical advantages will be highlighted.
