我们将开发基于飞秒激光脉冲序列的新型多维非线性光谱技术，以研究复杂分子系统中的超快过程和瞬态物质。分子系统将包括生物学上重要的蛋白质分子、复杂的合成聚合物、新型半导体材料和包括量子点在内的半导体量子结构。这些信息将极大地促进我们对基本动力学过程的理解，如宏观和超分子中的能量和电荷转移，动物体内氧的传输，光合作用，先进的光活性器件，以及新型半导体材料和半导体量子结构中的超快过程。

We will develop novel multidimensional nonlinear spectroscopic techniques based on sequences of femtosecond laser pulses to investigate ultrafast processes and transient species in complex molecular systems. The molecular systems will include biologically important protein molecules, complex synthetic polymers, new semiconductor materials and semiconductor quantum structures including quantum dots. This information will significantly advance our understanding of fundamental dynamical processes such as energy and charge transfer in macro- and supra-molecules, transport of oxygen in animals, photosynthesis, advanced photo-active devices, and ultrafast processes in new semiconductor materials and semiconductor quantum structures.
