Computer-Assisted UV-VIS Data Acquisition and Analysis in Undergraduate Laboratories

介绍了利用计算机辅助扫描紫外/可见/近红外分光光度计进行物理、分析和无机化学的六个新的和改进的实验室实验。学生将获得数字格式的动力学和光谱数据，并使用科学的电子表格（如RS/l）分析这些数据。二级动力学和酶动力学都会遇到；速率常数将用数值分析方法求得。二阶导数技术将应用于电子能谱，以阐明分子系统的激发态和复杂混合物的组成。将强调复杂的图形和统计资料的使用。受助人将与非联邦来源的NSF奖金相匹配。

Six new and modified laboratory experiments for physical, analytical, and inorganic chemistry are described that will take advantage of a computer-assisted scanning uv/vis/nir spectrophotometer. Students will acquire kinetic and spectroscopic data in digital format and analyze these data using a scientific spreadsheet, such as RS/l. Both second order and enzyme kinetics will be encountered; rate constants will be obtained using numerical methods of analysis. The second derivative technique will be applied to electronic spectra to elucidate the excited states of molecular systems and the composition of complex mixtures. Sophisticated graphics and the use of statistical information will be emphasized. The grantee will match the NSF award from non- Federal sources.
