For each of the following IR spectra, determine whether it agrees with the structure of a ketone, an alcohol, an aldehyde, a carboxylic acid, a primary amine or a secondary amine. (Hint: An absorption of average intensity around 2720 cm−1, accompanied by a carbonyl absorption band, is good evidence for the presence of an aldehyde group.)

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.
