Aug 15, 2017 · Nuclear magnetic resonance (NMR) spectroscopy is an analytical technique used to characterize organic molecules by identifying carbon-hydrogen frameworks. 1H NMR determines types and numbers of hydrogen atoms, while 13C NMR determines types of carbon atoms.
Aug 6, 2012 · Nuclear magnetic resonance (NMR) spectroscopy uses radio waves to analyze atomic nuclei and determine physical and chemical properties of molecules. There are two main types of NMR spectroscopy: 1H NMR, which identifies types and numbers of hydrogen atoms in a molecule, and 13C NMR, which identifies types of carbon atoms.
