Fourier Transform Infrared Spectroscopy

化学系正在购买一台傅里叶变换红外光谱仪（FTIR），以改善中级和高级实验室教学，并提高本科生的研究能力。在仪器分析课程中，学生通过测定汽车尾气中一氧化碳的含量来学习FTIR光谱法的定量能力。在有机化学课程中，他们对未知的醇、醛或酮进行基于计算机的光谱搜索。在物理化学课程中，他们观察和测量双原子和一些多原子气体的旋转精细结构中的同位素和量子统计效应。本科生的研究项目涉及结构测定和复杂样品的研究，如聚合物和薄膜，也进行。

The Chemistry Department is purchasing a Fourier Transform infrared spectrometer (FTIR) to improve intermediate and advanced laboratory instruction and to enhance undergraduate research capabilities. In the instrumental analysis course, students study the quantitative capabilities of FTIR spectrometry by determining the amount of carbon monoxide in automobile exhaust. In the organic chemistry course, they conduct computer-based spectral searches of an unknown alcohol, aldehyde or ketone. In the physical chemistry course they observe and measure isotope and quantum statistical effects in the rotational fine structure of diatomic and some polyatomic gases. Undergraduate research projects involving structure determination and the study of complex samples, such as polymers and films, are also carried out.
