Computer Interfaced Experiments for General Chemistry and Physical Chemistry Laboratories

摘要：在普通化学和物理化学实验室中引入计算机接口实验。六个实验被引入普通化学，涉及计算机与传感器接口，用于收集实验数据。使用SERAPHIM项目人员设计的温度探头、色度计接口或pH计接口。Lotus 1-2-3和Lotus Measure作为入门级的模板。实验包括化学动力学;量热法和反应热;从凝固点下降的分子量;计算机驱动的滴定来测量平衡;气相色谱法;和统计和误差分析。在物理化学中，学生正在做一些相同实验的高级方面，以及使用计算机通过显示波函数和考虑键长变化来分析原子和分子轨道。受赠人正在匹配来自非联邦来源的奖励。

ABSTRACT: Computer interfaced experiments are being introduced into the general chemistry and physical chemistry laboratories. Six experiments are being introduced into general chemistry involving computers interfaced with sensors for the gathering of experimental data. Temperature probes, colorimeter interfaces or pH meter interfaces designed by project SERAPHIM staff are being used. Lotus 1-2-3 and Lotus Measure are serving as templates at the introductory level. Experiments include chemical kinetics; calorimetry and heat of reaction; molecular weight from freezing point depression; computer driven titration to measure equilibrium; gas chromatography; and statistics and error analysis. In physical chemistry the students are doing advanced aspects of some of these same experiments as well as using the computers for analysis atomic and molecular orbitals through display of wave functions and the consideration of changes in bond length.
