Nonlinear Vibronic and Electronic Spectroscopy of Molecules in the Condensed Phase

安德烈亚斯·阿尔布雷希特得到了实验物理化学计划的支持，继续他对凝聚相中分子的非线性振动和电子光谱的研究。他将使用理论和实验方法来研究手性的非线性测量。系统在各向同性介质中，测量是在电偶极子水平上。具体地说，他将研究五阶奇波混频，将其作为二维核磁共振的超快光学模拟。手性体系在化学和物理学中处于核心地位。这些研究将提供支持手性的系统的信息，否则这些信息是无法获得的。尤其值得注意的是，这些方法将具有解析生物动力学所需的时间分辨率。由于在溶液中应用于具有生物意义的分子，这些研究将在远远超出化学或化学物理的领域产生重大影响。

Andreas Albrecht has support from the Experimental Physical Chemistry Program to continue his studies on nonlinear vibronic and electronic spectroscopy of molecules in the condensed phase. He will use theoretical and experimental methods to investigate nonlinear measurements of chirality. The systems are in isotropic media and measurements are at the electric dipole level. Specifically he will study fifth order odd-wave mixing as an ultrafast optical analog to 2D NMR. Chiral systems are central in chemistry and physics. These studies will yield information about systems that support chirality that is otherwise non-attainable. Especially noteworthy is the fact that these methods will have the time resolution required to resolve biological dynamics. Due to the applications to biologically-interesting molecules in solution, these studies will have a significant impact in areas well beyond chemistry or chemical physics.
