Concept Introduction:
A method by which structure of compound is determined by the interaction between matter and electromagnetic radiation is called spectroscopy. A spectroscopic technique in which infrared radiation is used for structural study is called IR spectroscopy.
Proton NMR spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group.
