Introduction to Infrared Spectroscopy

This module explores the various aspects of infrared spectroscopy – all the way from basic theory to advanced experimentation. We discuss the various molecular vibrations and infrared active modes and show you around the features of both dispersive and FT-IR instruments. We consider the important choices and variables associated with sample preparation and spectral acquisition and processing as well as discussing the important features of library searching.

Topics include:

• Electromagnetic radiation and infrared spectroscopy
• Molecular vibrations and infrared active modes
• Typical infrared absorption signals
• Principles and equipment of dispersive and FTIR instrumentation
• Sample preparation and data acquisition
• Infrared experiment types – what do you need to know?
• Attenuated total reflectance (ATR)
