Coherent Multidimensional Spectroscopy

Coherent multidimensional spectroscopy (CMDS) borrows heavily from the powerful two-dimensional Fourier transform (2D FT) NMR techniques that developed following the seminal paper by Ernst published in 1976 in The Journal of Chemical Physics.¹ CMDS reveals structure, dynamics and fluctuations that are obscured in conventional linear and nonlinear optical spectroscopies, enabling new insights into the structure and function of complex molecules, aggregates and materials. With advances in the production, manipulation and characterization of broadband laser sources, CMDS has been extended to new frequency regimes. Novel CMDS approaches that combine disparate frequencies are under development. Theoretical and computational tools for the simulation of CMDS experiments are driving new experimental approaches and enabling the interpretation of CMDS measurements on an increasingly diverse range of systems. This special issue celebrates the progress made in pushing the experimental and theoretical frontiers of CMDS.
