Label each statement as True or False.a. When a nucleus is strongly shielded, the effective field is larger than the applied field and the absorption shifts downfield.b. When a nucleus is strongly shielded, the effective field is smaller than the applied field and the absorption is shifted upfield.c. A nucleus that is strongly deshielded requires a lower field strength for resonance. d. A nucleus that is strongly shielded absorbs at a larger δ value.

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.
