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.

A researcher employed at Phenomenal Phenols, Inc. has been asked by her supervisor, O. H. Gruppa, to identify a compound A that was isolated from natural sources. Compound A, mp 129–130 °C, is soluble in NaOH solution and in hot water. The IR spectrum of compound A shows prominent absorptions at 3300–3600 cm-1 (broad) and 1680 cm1; the EI mass spectrum of compound A has prominent peaks at mlz = 166 and 107, and the CI mass spectrum has an M + 1 peak at m/z = 167. The NMR spectrum of compound A is given. Titration determined that compound A has two acidic groups with pKa values of 4.7 and 10.4. The UV spectrum of compound A is virtually unchanged as the pH of a solution of compound A is raised from 2 to 7, but the Amax shifts to much higher wavelength when compound A is dissolved in 0.1 M NAOH solution. chemical shift, Hz 2400 2100 1800 1500 1200 900 600 300 2H 1H low-field region: 2H 7.7 Hz 1H 7.7 Hz 2H 12 11 10 9 Ppm (8) 13 2H 8 7 6. 4 1 chemical shift, ppm (8) Propose a structure for…
