Improvement of UV-Visible Spectroscopy at Roanoke College

该项目将通过将最先进的紫外可见光谱学融入物理化学、仪器分析和生物化学的实验室课程，显著增强罗阿诺克学院的本科生化学课程。为该项目获得的计算机控制的紫外可见分光光度计为罗阿诺克学院的学生提供了以前没有的功能：确定吸光度随时间的变化，测量不同温度下的光谱，并获得非常高分辨率的光谱。现有的实验将得到实质性的改进，新的实验将加入课程。例如，对Co(II)平衡体系的研究，从光谱数据确定热力学函数，以及酶动力学的研究。该项目将让罗阿诺克学院的学生体验紫外可见光谱方面的现代技术。

This project will enhance significantly the undergraduate chemistry curriculum at Roanoke College by incorporating state-of-the-art UV- visible spectroscopy into laboratory courses in physical chemistry, instrumental analysis, and biochemistry. The computer-controlled UV- visible spectrophotometer acquired for this project affords capabilities not previously available to students at Roanoke College: determining absorbance as a function of time, measuring spectra at various temperatures, and obtaining spectra with very high resolution. Current experiments will be improved substantially, and new experiments will be added to the curriculum. Examples include a study of a Co (II) equilibrium system, determination of thermodynamic functions from spectroscopic data, and investigations of enzyme kinetics. The project will give students at Roanoke College experience with modern technology in UV-visible spectroscopy.
