项目摘要

Electron Paramagnetic Resonance (EPR) spectroscopy is a vital research tool in many areas of chemistry and the only analytical method that allows direct detection of organic radical and transition metal paramagnetic species. Our departmental Bruker EPR spectrometer was acquired in 1998 and has never been upgraded. Due to the low sensitivity of this instrument, research is currently limited to simple paramagnetic systems and routine EPR experiments. Despite this, our instrument has great potential to be upgraded to the next generation in EPR technology and perform at a level comparable to a brand new instrument, yet at a fraction of the price. This will open the door to new areas of research, such as challenging paramagnetic transition metal complexes – a key focus of several research programs in our department.***The proposed upgrade package is designed to provide maximum performance and sensitivity by way of a high sensitivity X-band resonator, a digitally-enhanced EMX console, a liquid helium variable temperature unit, liquid nitrogen adapter kit and Xenon software package. The high sensitivity resonator provides sensitivity and resolution far superior to our current probe, while the digitally-enhanced console offers improved dynamic range for both signal amplitude and field, allowing even the weakest signals to be easily detected. The helium low temperature unit is essential for studying first row transition metal compounds by EPR spectroscopy. Finally, the Xenon software is user-friendly and extensive in its capabilities, enabling both spectral fitting and quantitative spin count measurements to be easily conducted. Further, the upgrade package is compatible with our robust electromagnet; hence, both the magnet and its power supply can be excluded from this proposal.***This upgrade is essential for researchers at the University of Calgary to maintain competitive research programs. The increased sensitivity and new detection limits will open the door to new avenues of research, and allow more research groups to explore EPR as a key spectroscopic technique.**
电子顺磁共振(EPR)光谱是化学许多领域的重要研究工具,也是唯一可以直接检测有机自由基和过渡金属顺磁物质的分析方法。我们部门的布鲁克EPR光谱仪于1998年收购,从未升级过。由于该仪器的灵敏度较低,目前的研究仅限于简单的顺磁系统和常规EPR实验。尽管如此,我们的仪器有很大的潜力升级到下一代EPR技术,并在与全新仪器相当的水平上运行,但价格只是一小部分。这将为新的研究领域打开大门,例如挑战顺磁性过渡金属配合物-这是我们部门几个研究项目的重点。***拟议的升级包旨在通过高灵敏度x波段谐振器、数字增强EMX控制台、液氦变温单元、液氮适配器套件和Xenon软件包提供最大的性能和灵敏度。高灵敏度谐振器提供的灵敏度和分辨率远远优于我们目前的探头,而数字增强控制台为信号幅度和场提供了改进的动态范围,即使是最弱的信号也可以轻松检测到。氦低温装置是用EPR光谱研究第一排过渡金属化合物所必需的。最后,Xenon软件是用户友好的,功能广泛,使光谱拟合和定量自旋计数测量都很容易进行。此外,升级包与我们强大的电磁铁兼容;因此,磁铁和它的电源都可以排除在这个提议之外。***这一升级对于卡尔加里大学的研究人员保持有竞争力的研究项目至关重要。灵敏度的提高和新的检测限将为新的研究途径打开大门,并允许更多的研究小组将EPR作为一种关键的光谱技术进行探索
