Spectroscopy involves an interaction between matter and light . (EMR). Light can be thought of as waves of energy or packets (particles) of energy called photons. Properties of light waves include wavelength and frequency. Spectroscopy . . Is the interaction between matter and electromagnetic radiation (light). . Spectroscopy is commonly used in chemistry to detect, identify, and quantify information about different atoms and molecules. 1 FALL 2017 CHEM 430 IR SPECTROSCOPY Long Lecture Play Dr. Justik Introduction The method provides a rapid and simple method for observing the functional group species present in an organic molecule 1 IR-Spectroscopy IR region The part of electromagnetic radiation between the visible and microwave regions 0.8  m to 50  m ( 12,500 cm -1 - 200 cm -1 ) is called IR region Most interested region in Infrared Spectroscopy is between 2.5 Chapter 5.
