Femtosecond vibrational spectroscopy of liquids, solutions, and biomolecules

该博士项目涉及一种称为飞秒光学克尔效应（OKE）光谱学的技术，该技术可以在飞秒到纳秒的时间尺度上测量分子动力学。信号的傅里叶变换产生拉曼光谱，揭示了分子如何振动、晃动、旋转和扩散。我们已经成功地使用这种技术来研究，例如，室温离子液体，相变和蛋白质的相干动力学。我们将把这种技术应用于溶液或生物分子。与我们的合作者，我们将能够联合收割机结合我们的OKE技术与二维红外（2D-IR）光谱的互补技术。博士生将与一组具有超快技术，化学物理和显微镜经验的博士后研究人员一起工作。

The PhD project involves a technique called femtosecond optical Kerr-effect (OKE) spectroscopy, which measures molecular dynamics on a timescale from femtoseconds to nanoseconds. Fourier transformation of the signal results in a Raman spectrum that reveals how the molecules vibrate, rattle, rotate, and diffuse. We have been using this technique successfully to study, for example, room temperature ionic liquids, phase transitions, and the coherent dynamics of proteins. We will be applying this technique to either solutions or biomolecules. With our collaborators, we will be able to combine our OKE technique with the complementary technique of two-dimensional infrared (2D-IR) spectroscopy. The PhD student will be working alongside a team of postdoctoral researchers with experience in ultrafast techniques, chemical physics, and microscopy.
