Nuclear magnetic resonance spectroscopy

Nuclear magnetic resonance (NMR) spectroscopy is usually combined with infrared (IR) spectroscopy for the complete analysis of the structure of an unknown molecule. IR spectroscopy is used to detect a functional group in the sample, whereas NMR spectroscopy detects number of atoms and their type in sample. NMR technique can detect many nuclei but mostly identifies carbon-hydrogen frameworks. In this chapter, we have comprehensively discussed the NMR spectroscopy, its types, basic mechanism along with its instrumentation, applications, advantages, and disadvantages.
