Two-Dimensional Optical Spectroscopy

Two-dimensional ultrafast spectroscopy in the IR, visible and UV spectral regions reveals the couplings between different degrees of freedom in molecules and materials. These coupled motions might be vibrational (observed by 2DIR spectroscopy), electronic (2DES) or might involve both electronic and vibrational degrees of freedom (2DEV spectroscopy).

Two-Dimensional Optical Spectroscopy

Two-dimensional optical spectroscopies are recognised as incisive spectroscopic tools to explore structure and dynamics of complex molecular systems. 2D electronic spectroscopy (2DES) allows the investigation of energy relaxation and transfer in molecules, nanomaterials and molecular aggregates. Two-dimensional vibrational spectroscopy (2DIR) is capable of probing the ground state structure and vibrational coupling of many chemical and biological systems.
