Creation of a Laser-Based Kinetics/Spectroscopy Laboratory

正在建立一个基于激光的动力学/光谱学实验室 为学生提供物理化学，仪器 分析，高分子化学实验室和本科 research. 有了这个设备，学生们进行实验， 深入了解化学和物理原理 在讲座中讨论。 实验室有两个 工具安排，其中每一个都可以很容易地适应 来做一些实验。 一种是利用稳态 激发实现拉曼散射，发射光谱， 荧光分析和光散射。 该系统 包括150 mW氩离子激发激光器和检测器， 系统由单色器、光电倍增管和 锁定放大器或静电计。 数据收集 在电脑控制下。 第二种安排的特点是 脉冲氮激光泵浦的染料激光激发源， 允许学生测量发光寿命， 脉冲探针实验 检测是通过 数字示波器

A laser-based kinetics/spectroscopy laboratory is being created to service students in physical chemistry, instrumental analysis, and polymer chemistry laboratories and undergraduate research. With this equipment, students perform experiments to gain insights into the chemical an physical principles discussed in lecture courses. The laboratory houses two instrumental arrangements, each of which can be easily adapted to perform a number of experiments. One utilizes steady-state excitation to effect Raman scattering, emission spectroscopy, fluorescence analysis, and light scattering. This system includes a 150 mW Argon-ion excitation laser and a detection system consisting of a monochromator, photomultiplier tube, and either a lock-in amplifier or electrometer. Data collection is under computer control. The second arrangement features a pulsed-nitrogen laser pumped dye laser excitation source that allows students to measure luminescence lifetimes and perform pulse-probe experiments. Detection is accomplished with a digital oscilloscope.
