Decide if each statement about NMR spectroscopy is true or false. Splitting is due to coupling between protons on adjacent carbon atoms. The number of peaks in a signal in a 1H-NNMR spectrum is determined by the number of hydrogens producing that signal. Splitting is due the interactions between to a carbon atom and the protons attached to that carbon atom.

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.
