Improvement in Advanced Laboratory Using an Instrumental Laboratory Timesharing Concept

教本科生使用现代化学仪器， 由于复杂性和复杂性， 工具和它们所基于的理论。这 这一情况加剧了安排实验的问题， 最合适的时间。克服这些困难的独特计划是 正在实施的化学系的学院的神圣 物理化学与仪器分析的交叉融合 实验室成一个连贯的三学期先进的实验室计划。 从基本的仪器实验室技术， 第一学期的挑战和先进的主题在第三 学期正在进行中。在第一学期， 利用快速数据采集能力的分时方法 紫外-可见（UV-VIS）快速扫描分光光度计和 傅里叶变换红外（FTIR）分光光度计使其成为可能 为所有学生同时进行一系列的介绍 光谱学实验在同一个学期，他们将 开始使用计算机作为数据站。高潮 学生的实验室经历发生在第三学期 他们把注意力集中在一些 具有挑战性和先进的技术， 化学研究，包括激光在化学中的应用， 用于研究快速反应和微型计算机。

Teaching undergraduates to use modern chemical instrumentation has become increasingly difficult due to the sophistication and complexity of both the instruments and the theory upon which they are based. This situation has aggravated the problem of scheduling experiments at the most opportune time. A unique plan to overcome these difficulties is being implemented by the Chemistry Department of the College of the Holy Cross by merging the Physical Chemistry and Instrumental Analysis Laboratories into a coherent three-semester advanced laboratory program. An orderly progression from basic instrumental laboratory techniques in the first semester to challenging and advanced topics in the third semester is being followed. During the first semester a unique timesharing approach utilizing the rapid data acquisition capabilities of a an ultraviolet-visible (UV-VIS) rapid scan spectrophotometer and a Fourier Transform Infrared (FTIR) spectrophotometer makes it possible for all students to concurrently carry out a series of introductory experiments in spectroscopy. During the same semester they will be introduced to the use of the computer as a data station. The culmination of the students' laboratory experience occurs in the third semester where they devote attention to projects centered around some of the challenging and advanced techniques essential to carrying out modern chemical research, including the use of lasers in chemistry, techniques for studying very fast reactions, and microcomputers.
