Concept explainers

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.

Identify the following spectra. Full credit is only given if all pertinent peaks are assigned on the spectrum (~5-6 peaks). Label the peaks on the spectrum and place the structure of the compound in the box on the lower left-hand corner of the spectrum (from the table below, no numbering scheme).It is highly advisable to use the tables provided in the infrared handout and lectureto avoid confusion caused by tables from different sources. You do not have to indicate the exact wavenumber of the peak.
