项目摘要

We apply for a transient 2D IR (infra-red) and EA (electronic absorption) spectrometer system consisting of a pump laser with two suitable OPAs, 2D EA spectrometer, 2D IR spectrometer, and the transient absorption add on. The instrument is key in various interdisciplinary and interfaculty initiatives within the university and with other academic cooperation partners. In addition to the already existing time-resolved 1D spectroscopies the proposed 2D spectroscopy setup can answer questions regarding how transitions between different electronic or vibrational states take place in more detail and provides both unique structural and kinetic information. In order to perform state of the art measurements, on one hand, and to keep our focus on the chemical experiments rather on developing and/or building our own spectrometer, on the other hand, we aim for well established commercially available spectrometer systems based on the pulse shaping technology. With the requested 2D spectrometer systems we could perform 2D spectroscopy throughout the complete visible range with the focus on the transitions between electronic states. Regarding the IR range we will be able to follow vibrational dynamics in the range 1000 – 3850 cm-1 (2600 – 10000 nm) which will be perfectly suited for the envisioned projects.

我们申请了瞬态2D IR（红外）和EA（电子吸收）光谱仪系统，该系统由一个带有两个合适的OPA的泵浦激光器、2D EA光谱仪、2D IR光谱仪和瞬态吸收附加装置组成。该仪器是大学内各种跨学科和跨学院倡议以及与其他学术合作伙伴的关键。除了已经存在的时间分辨1D光谱之外，所提出的2D光谱设置可以更详细地回答关于不同电子或振动状态之间的跃迁如何发生的问题，并提供独特的结构和动力学信息。为了进行最先进的测量，一方面，并保持我们的重点放在化学实验，而不是开发和/或建立我们自己的光谱仪，另一方面，我们的目标是建立良好的商业可用的光谱仪系统的基础上脉冲整形技术。使用所要求的2D光谱仪系统，我们可以在整个可见光范围内进行2D光谱分析，重点关注电子状态之间的跃迁。关于IR范围，我们将能够在1000 - 3850 cm-1（2600 - 10000 nm）范围内跟踪振动动力学，这将非常适合设想的项目。
