Structure and function of complex Molecules and biologically important compounds are explored by utilizing the coupling between molecular vibrations as a highly specific probe of the local molecular environment.
We use multi-dimensional Infrared spectroscopies to measure the time-evolution of molecular structure and vibrational coupling at equilibrium and during chemical reactions.
The data is displayed in two-dimensional frequency maps,
correlating coupled vibrational modes, similar to how 2D-NMR correlates coupled nuclear spins.
