Carbon-13 NMR
Carbon-13 nuclear magnetic resonance spectroscopy, commonly referred to as Carbon-13 NMR, is a powerful analytical technique utilized in organic chemistry for elucidating the structure and connectivity of carbon atoms within organic molecules. Unlike proton NMR, which focuses on the behavior of hydrogen nuclei, Carbon-13 NMR specifically examines the resonance frequencies of carbon-13 nuclei. This technique provides valuable insights into molecular composition, stereochemistry, and functional group environments, facilitating the identification and characterization of organic compounds with unparalleled precision and specificity.
