The Infrared (IR) microspectroscopy system was purchased in 2007 and installed at the Electrochemical Technology Centre (ETC) of the University of Guelph (UoG). It includes: (i) a Nicolet Nexus 870 FT-IR spectrophotometer, (ii) a PM-IRRAS Module for Nicolet Nexus 870, (iii) a Continuum FT-IR Microscope, (iv) a diamond attenuated total internal reflection (ATR) accessory, and (v) an IR purge gas generator. The IR microspectroscopy system has been configured to characterize various materials and interfaces, including solid-solution and electrochemical interfaces. It provides several advanced spectroscopic techniques such as localized ATR spectroscopy, photon polarization infrared reflection absorption spectroscopy (PM IRRAS), subtractively normalized interfacial Fourier transform spectroscopy (SNIFTIRS), and surface enhanced infrared reflection absorption spectroscopy (SEIRAS). The IR microspectroscopy facility has been extensively used over the last 14 years. Although the IR microscope, ATR, and gas generator continue to function very well, the FT-IR spectrophotometer and PM-IRRAS Module have reached the limits of their lifespans and are dysfunctional. As the suppliers and associated servicing for the 870 FT-IR spectrophotometer and PM-IRRAS Module for the Nicolet Nexus 870 have been discontinued, it is necessary for us to replace them with the new Nicolet iS50R FT-IR spectrophotometer and its advanced PM-IRRAS Module, which incorporate the latest electronic and digital technology for advanced continuous scan, step-scan, and dual-channel applications. The proposed critical upgrade will enable a completely functioning system that is urgently required to support a number of NSERC funded research programs at UoG. In particular, the innovative research programs of the applicant (Professor A. Chen) and co-applicants (Professor L. Chen, J.R. Dutcher and J. Lipkowski), and the major users (Professor F.-I. Auzanneau, H. Li, E. Pensini and Dr. Q. Wang). The IR microspectroscopy system is a unique research facility at UoG and this region. It is located at the ETC, and is easily accessible by students and researchers on campus and across this region. The Manager of the ETC will continue to maintain the facility and to provide hands-on training. All trained students, postdoctoral fellows, and research associates will run their samples and analyze the spectra. It is anticipated that the upgraded IR microspectroscopy system will be in operation every day for over 180 hours per month by the research teams of the applicant, co-applicants and major users alone. Additional time will be required by users from the Departments of Chemistry and Physics, and the School of Engineering. It is essential for student training and will facilitate further regional, national, and international collaborations toward the development of advanced clean technologies to address increasingly critical energy, environmental, and health issues.

红外 (IR) 显微光谱系统于 2007 年购买并安装在圭尔夫大学 (UoG) 电化学技术中心 (ETC)。它包括：(i) Nicolet Nexus 870 FT-IR 分光光度计，(ii) Nicolet Nexus 870 的 PM-IRRAS 模块，(iii) Continuum FT-IR 显微镜，(iv) 金刚石衰减全内反射 (ATR)附件，以及 (v) 红外吹扫气体发生器。红外显微光谱系统已配置为表征各种材料和界面，包括固溶体和电化学界面。它提供了多种先进的光谱技术，例如局域 ATR 光谱、光子偏振红外反射吸收光谱 (PM IRRAS)、减法归一化界面傅里叶变换光谱 (SNIFTIRS) 和表面增强红外反射吸收光谱 (SEIRAS)。红外显微光谱设备在过去 14 年中得到了广泛应用。尽管红外显微镜、ATR 和气体发生器继续运行良好，但 FT-IR 分光光度计和 PM-IRRAS 模块已达到其使用寿命极限并且无法正常工作。由于 870 FT-IR 分光光度计和 Nicolet Nexus 870 的 PM-IRRAS 模块的供应商和相关服务已停止，我们有必要用新的 Nicolet iS50R FT-IR 分光光度计及其先进的 PM-IRRAS 取代它们模块，融合了最新的电子和数字技术，适用于先进的连续扫描、步进扫描和双通道应用。拟议的关键升级将启用一个功能齐全的系统，该系统是支持 UoG 的许多 NSERC 资助的研究项目所迫切需要的。特别是申请人（A. Chen教授）和共同申请人（L. Chen教授、J.R. Dutcher和J. Lipkowski教授）以及主要用户（F.-I. Auzanneau教授、H. Li教授）的创新研究项目、E. Pensini 和 Q. Wang 博士）。红外显微光谱系统是 UoG 和该地区的独特研究设施。它位于 ETC，校园内和整个地区的学生和研究人员都可以轻松访问。 ETC 经理将继续维护该设施并提供实践培训。所有受过培训的学生、博士后研究员和研究员将运行他们的样品并分析光谱。预计升级后的红外显微光谱系统将由申请人、共同申请人和主要用户的研究团队每天运行，每月运行时间超过180小时。化学系、物理系以及工程学院的用户将需要额外的时间。它对于学生培训至关重要，并将促进进一步的区域、国家和国际合作，开发先进的清洁技术，以解决日益重要的能源、环境和健康问题。
