Infrared spectroscopy deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light. It covers a range of techniques, which is mostly based on absorption spectroscopy. It can also be used to identify and study chemicals.  Its concept can generally be analyzed in three ways- by measuring reflection, emission, absorption.
