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

这项应用旨在将现有的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)。这将允许将目前可用的测量选项主要扩展到时间分辨实验。这一升级还包括在辐照下进行时间分辨测量的可能性，以及在4-300K之间精确控制温度。新的测量选项将用于深入研究，以深入研究分子磁体和Q比特中的基本相互作用，并特别关注以更好地了解和控制它们的结构-性能关系。此外，拟议的辐照时间分辨ESR测量系统旨在显著拓宽研究光催化循环中的自由基中间体、确定分子物种中三重态的功能以及分子二元体和三元体中的电荷分离态的选择范围。建议的系统将允许对自由基聚合过程中发生的过程进行基本的了解，从而有助于对它们的深入了解。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”范围内的科学发展方面。拟议的升级将进一步加强无机分子化学、高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.
