Acquisition of an FTIR Spectrometer for Biochemical and Materials Research and Education

凭借化学研究仪器和设施：多用户(CRIF：MU)计划的这一奖项，来自佛罗里达大学的Daniel Talham教授及其同事Alexander Angerhofer、Lisa McElwee-White、Juan Nino和Adam Veige将获得具有远红外功能的傅立叶变换红外(FTIR)光谱仪、电化学池和停流系统。该奖项将加强各级的研究培训和教育，特别是在下列研究领域：(A)化学气相沉积(CVD)和原子层沉积(ALD)铜屏障的机理方法，(B)野生型和突变型草酸脱羧酶的酶动力学，(C)二氧化碳还原电催化剂的设计和评价，(D)三阴离子夹铬(V)-氧物种氧原子转移的停流和电化学红外分析，(E)有机合成中的FTIR研究，以及(F)研究超导体和电介质中的结构和电关系。傅里叶变换红外光谱(FTIR)是一种用于获得固体、液体或气体吸收或发射的红外光谱的技术。FTIR光谱仪同时收集宽光谱范围内的光谱数据，并使用数学算法转换原始数据以提供光谱。这类现代仪器开辟了利用波长比可见光更长的电磁辐射进行红外光谱分析的新应用。停流系统允许快速混合以研究化学动力学，而电化学池允许使用直流电来氧化或还原化合物，同时研究光谱的变化。该仪器将位于光谱学设施中，将由大量研究人员和学生使用。

With this award from the Chemistry Research Instrumentation and Facilities: Multi-user (CRIF:MU) program, Professor Daniel Talham and colleagues Alexander Angerhofer, Lisa McElwee-White, Juan Nino and Adam Veige from the University of Florida will acquire a Fourier transform infrared (FTIR) spectrometer with far infrared capabilities as well as an electrochemical cell and a stop-flow system. The award will enhance research training and education at all levels, especially in areas of study such as (a) mechanism-based approaches for chemical vapor deposition (CVD) and atomic layer deposition (ALD) of copper barriers, (b) enzyme kinetics of wild-type and mutant oxalate decarboxylase, (c) design and evaluation of electrocatalysts for carbon dioxide reduction, (d) stopped-flow and electrochemical IR analysis of oxygen atom transfer from trianionic pincer chromium(V)-oxo species, (e) studies of FTIR in organic synthesis, and (f) studies of structure and electrical relationships in superconductors and dielectrics.Fourier transform infrared (FTIR) spectroscopy is a technique used to obtain an infrared spectrum of absorption or emission of solids, liquids or gases. An FTIR spectrometer simultaneously collects spectral data in a wide spectral range and transforms the raw data using a mathematical algorithm to provide a spectrum. This type of modern instrumentation has opened up new applications of infrared spectroscopy using electromagnetic radiation with wavelengths longer than those of visible light. The stop-flow system allows rapid mixing for the study of chemical kinetics and the electrochemical cell allows use of direct current to oxidize or reduce compounds and simultaneously study the changes in the spectra. The instrumentation will be located in a spectroscopy facility and will be used by a large number of researchers and students.
