The O of the hydroxyl of methyl salicylate is involved is resonance with the ring. Use carefully-drawn resonance structures to explain which of the carbons of the ring become cationic or anionic. Then state what effect this resonance is expected to have on the ¹H-NMR chemical shift of the H attached to those carbons.

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.
