Course Catalog

Across the Spectrum: Infrared Spectral Interpretation OnDemand

An overview of how to determine unknown molecular structures from infrared spectra. This course begins with how molecules absorb infrared radiation, and what peak positions, heights, and widths mean. Next, a systematic, 10-step strategy to successfully interpret spectra is presented. The bulk of the course is a discussion of important infrared bands of a number of economically important molecules including alkanes, aromatics, alcohols, esters, and amines. Special discussions of polymers and inorganics are included. The course concludes with a practical discussion of how library searching and spectral subtraction make interpreting spectra faster and easier. Interpretation workshops, where attendees interpret unknown spectra with the help of the instructor, are held throughout the course.

This exciting course can be purchased a la carte. Each module is individually priced and will be held on a rolling basis throughout the year to accommodate your schedule and budget.
