UV-visible spectroscopy

This webpage, part of a larger project "Understanding Chemistry", provides a solid introduction to UV-vis spectroscopy suitable for use in introductory chemistry and introductory analytical chemistry courses. The UV-vis pages discuss UV-vis light, absorption, Beer's law, the double-beam spectrometer, and introduce some standard applications of UV-vis spectroscopy. Explication is clear and thoughtful. Judicious…

How an Interferogram is Produced – An Animated Explanation

This animated tutorial explains the principles behind the operation of the interferometer in an FTIR spectrometer.  The tutorial examples start from a single wavelength so that students can begin with an easier example. After that, the examples explain the superposition of multiple wavelengths. Finally, the tutorial explains the connection between an interferogram and a frequency domain…

Basic Concepts of Optical Microscopy

A comprehensive primer focused on the basic optical microscope, as well as the electron, confocal, polarizing, and stereoscopic microscopes. Virtual microscopes allow the user to simulate the use of a variety of real-life microscopes. There are galleries of photomicrographs illustrating a variety of specimens. This website provides complete instructional materials on the theory of light and…

The Evolution of a Laboratory Syllabus for Quantitative Analysis

The paper contains a syllabus of a redesigned quantitative analysis lab. In its new form, the lab is almost entirely instrumental. The description has sufficient detail to assist a fellow instructor to adopt the experiments. A rationale for the experiments and the lab protocols has also been provided.The website is available here .
