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.

本应用程序旨在将现有的连续波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扩展到时间分辨实验。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，以产生对分子磁体和q位的基本相互作用的见解，特别关注更好地理解和控制它们的结构-性质关系。此外，提出的辐照时间分辨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，分子物种中功能确定的三重态以及分子二联体和三元组中电荷分离态的选择。提出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了解。所要求的EPR分光仪将持续加强化学研究所的基础设施和竞争力，特别是在跨区域234“CataLight”合作研究中心的科学发展方面。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。
