Upgrade of the present ESR spectrometer to a pulsed FT/CW-ESR spectrometer

该应用程序旨在将现有的CW电子自旋共振光谱仪（CW-ESR）升级为FT/CW-ESR光谱仪（脉冲操作）。这将使目前可用的测量选项向时间分辨实验的重大扩展成为可能。升级还包括在辐照下进行时间分辨测量的可能性，以及在4-300 K之间精确控制温度。新的测量选项将用于深入研究，以深入了解分子磁体和Q-bit中的基本相互作用，特别关注更好地理解和控制它们的结构-性质关系。此外，建议的辐照时间分辨ESR测量系统的目的是显着扩大的选择，对调查的自由基中间体在光催化循环，功能确定三重态的分子物种，和电荷分离的状态在分子的二分体和三分体。拟议的系统将允许获得基本的洞察过程中发生的自由基聚合，从而有助于他们的深入理解。所要求的EPR光谱仪将可持续地加强化学研究所的基础设施和竞争力，特别是在合作研究中心Transregio 234“CataLight”的科学发展方面。此次升级将进一步加强无机分子化学、大分子化学和物理化学之间的合作，并将开辟新的合作机会。

This application is intended to upgrade existing CW electron spin resonance spectrometer (CW-ESR) to a FT/CW-ESR spectrometer (pulsed operation). This will allow for a major extension of the currently available measurement option towards time-resolved experiments. The upgrade also includes the possibility of time-resolved measurement under irradiation, as well as precise control of the temperature between 4-300 K. The new measurement options will be used for in-depth studies to generate insights into the basic interactions in molecular magnets and Q-bits with a particular focus to better understand and control their structure-property relationships. In addition, the proposed irradiated time-resolved ESR measurement system is intended to significantly broaden the options towards the investigation of radical intermediates in photocatalytic cycles, function-determining triplet states in molecular species, and charge-separated states in molecular dyads and triads. The proposed system will allow to gain fundamental insight into processes that take place during radical polymerizations and thus contribute to their in-depth understanding. The requested EPR spectrometer will will provide a sustainable strengthening of the infrastructure and competitiveness of the chemical institutes, especially with regard to the scientific development in the context of the Collaborative Research Center Transregio 234 "CataLight". The proposed upgrade will further strengthen the cooperation between inorganic molecular chemistry, macromolecular chemistry and physical chemistry, and will open up new opportunities for collaboration.
