The interaction of light with substance to identify the substance properties called spectroscopy. Chemical analysis can be done both qualitatively and quantitatively by many analytical methods, but a large area of analysis is done using spectroscopy, in which IR and NMR Spectroscopy are the most useful. Infrared spectroscopy (IR) is a potent tool to identify various functional groups, whereas to determine the structure of organic compound the Nuclear magnetic resonance (NMR) spectroscopy is one of the valuable techniques.
Both are the forms of absorption spectroscopy, however, they didn’t work the same. IR spectroscopy means infrared spectroscopy and NMR spectroscopy means nuclear magnetic resonance spectroscopy.
The basic difference between IR and NMR spectroscopy is that the Infrared spectroscopy determines the frequency of vibrations between atoms in a molecule, and it used to identify the functional groups present in the matter. NMR calculates the nuclear magnetic resonance, where the frequency of resonance is influenced by electrons protecting the nucleus and it used to determine the structure of organic compounds.
