found: Multidimensional spectroscopy, via University of Michigan Department of Chemistry Kubarych Group website, July 1, 2020(There are many different ways to study the properties of molecules. Optical spectroscopy has proven to be one of the most useful and general approaches; traditional linear spectroscopy is incapable of distinguishing, for example, whether two spectral features arise from transitions on the same molecule, or from different molecules within a mixture. Even with only a single chemical species, 1D spectroscopy can say nothing about whether two transitions are close together or far apart in space. These ambiguities can be overcome using multidimensional spectroscopy (MuDSy) where cross-peaks in the 2D spectrum directly map to couplings that are highly dependent on distance and angular orientation. MuDSy techniques are both nonlinear and at least two-dimensional; The basic idea of multidimensional spectroscopy is that we can observe the coupling between transitions in condensed phase molecules. The coupling is highly dependent on distance and angles so we can determine structural information. Since the laser pulses we use are all less than [approx.]150 fs, we can measure structrual evolution on sub-picosecond timescales)
