NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Expert Solution

Overview

The H on the carbon atom adjacent to electronegative atom O will be highly deshielded.
Their chemical shifts range from 4-5 ppm.
Based on the peak splitting pattern we can determine the particular molecules.
Also, the peak height is based on the number of H atoms in the same chemical environment.
