Nonlinear Vibronic and Electronic Spectroscopy in Molecules in the Condensed Phase (Chemistry)

实验物理化学的这项资助支持以下研究： Andreas C. Albrecht在非线性光学领域的研究 光谱学，一个与吸收有关的科学领域， 一个以上的光子同时产生。 这个项目被认为是阿尔布雷希特博士研究的延续 光与物质相互作用的基本方面。在这里，他将携带 三个具体项目。 第一个希望使用三色 共振四波混频提取横向和纵向 电子振动能级的弛豫时间， 拓宽了电子跃迁。 第二种会产生共振 凝聚相分子溶液的三次谐波产生 可行的光谱学和研究它与三光子吸收一致 在同一个系统上进行测量。 最后一个实验项目是 提出了检查光诱导的额外共振 理论上预测的次级辐射。 后者 代表改变拉曼/共振荧光的第一次尝试 通过控制激发光的性质来平衡。

This grant in Experimental Physical Chemistry supports the research of Professor Andreas C. Albrecht in the area of nonlinear optical spectroscopy, a scientific field that is concerned with the absorption of more than one photon of light simultaneously. This project is considered a continuation of Dr. Albrecht's research on fundamental aspects of light-matter interactions. Here he will carry out three specific projects. The first hopes to use three-color resonant fourwave mixing to extract transverse and longitudinal relaxation times of vibronic levels that make up inhomogeneously broadened electronic transitions. The second will develop resonant third harmonic generation from condensed phase molecular solutions as a viable spectroscopy and study it in unison with three-photon absorption measurements on the same system. Finally an experimental project is proposed which examines light induced extra resonances in resonance secondary radiation that have been predicted theoretically. The latter represents a first attempt to alter the Raman/resonance fluorescence balance by controlling the properties of the exciting light.
