I will overview a powerful new technique in physical chemistry, Angle-Resolved Coherent (ARC) wave-mixing.
This technique is unique in allowing molecular excitons (coherent superposition states) to be distinguished from incoherent energy transfers instantaneously. It does this by directly projecting their signatures into orthogonal spatial dimensions, and without post-processing. Using this we have unveiled an ordered evolution of exciton state energies in a light harvesting protein, in-vitro and at physiological temperature.
This idea of mapping a laser wave-mixing emission against its angle of emission is broadly applicable. We'll discuss the future mapping of molecular excitations spanning the UV to the near-infrared simultaneously, and we'll look at a future scheme for revealing protein structure dynamically, based on an instantaneous mapping of vibration couplings.
