Homework Answers
• Nuclear magnetic resonance
spectroscopy is one of the techniques in analytical chemistry that is widely used to determine the purity of sample and also to predict the structure of the organic compounds.
• The 
spectroscopy is a phenomenon that is observed when the frequency of nuclei of atoms (sample) resonates with the frequency of rotating magnetic field.
• 
Spectroscopy gives the information about nonequivalent protons or nonequivalent carbons present in the structure.
