Microcomputer Applications for Chemistry Laboratories

化学系正在购买8台微型计算机及其相关的外围设备和软件，用于普通化学、物理化学和仪器分析的实验室课程。这些实验室课程相互协调，使学生从连贯地介绍计算机在化学中的应用中受益；包括数据分析、与实验的接口和理论计算。作为该项目的一部分，正在为这些实验室开发新的基于计算机的实验。除了在特定课程中使用外，这些计算机还可供所有化学学生在任何计划外的时间使用。在普通化学课程中，学生被介绍到计算机以收集数据、分析和解决问题；包括接触电子表格、图表和方程求解软件。使用各种传感器，如热敏电阻、热电偶和光电二极管。在定量分析过程中，进行了高效液相色谱阴离子分析实验。在仪器分析课程中，关于使用计算机进行数据采集、控制和分析的教学建立在前面课程中获得的经验的基础上。在物理化学课程中，要计算分子的几何构型和振动频率，如二氧化硫。

The Department of Chemistry is purchasing 8 microcomputers with associated peripherals and sofware for use in laboratory courses in general chemistry, physical chemistry, and instrumental analysis. These laboratory courses are coordinated with one another so that students receive the benefits of a coherent introduction to the applications of computers in chemistry; including data analysis, interfacing to experiments, and theoretical computations. As part of this project, new computer-based experiments are being developed for these labs. In addition to their use in specific courses, these computers are available to all chemistry students at all unscheduled times.In the general chemistry course, students are introduced to computers for data collection, analysis and problem solving; including exposure to spreadsheet, graphing and equation-solving software. Various transducers, such as thermistors, thermocouples, and photodiodes are used. In the quantitative analysis course, experiments are performed involving anion analysis by high performance liquid chromatography. In the instrumental analysis course, instruction in the use of computers for data acquisition, control, and analysis build upon the experience gained in earlier courses. In the physical chemistry course, the geometry and vibrational frequencies of a molecule, such as SO2 are calculated.
