Multidimensional optical spectroscopies are the most incisive probes of ultrafast dynamics in condensed phase systems. These experimental techniques combine broadband spectral resolution with ultrafast (sub-20 fs, where 1 fs = 1 x 10^-15 s) time resolution to interrogate the coupled electronic and nuclear dynamics that underpin the functionality of a whole plethora of photoactive molecules and materials.Two-dimensional electronic spectroscopy and two-dimensional electronic-vibrational spectroscopy will be used to track the time-evolving electronic-nuclear dynamics of biomolecules in solution, proteins and nanomaterials, and investigate how the chromophore-environment interactions alter/dictate the ensuing photochemistry.

多维光学光谱是研究凝聚相系统中超快动力学的最深入的探针。这些实验技术结合了宽带光谱分辨率和超快(1 fS=1×10^-15 S)时间分辨率来研究支持大量光活性分子和材料功能的耦合电子和核动力学。二维电子光谱和二维电子振动光谱将被用于跟踪生物分子在溶液、蛋白质和纳米材料中随时间演变的电子-核动力学，并研究生色团与环境的相互作用如何改变/支配随后的光化学。
