WebA carbon-13 NMR spectrum is useful in choosing between possible isomers. This video shows you how to interpret one. WebNuclear Magnetic Resonance Spectroscopy, or NMR Spectroscopy, can be used to identify any isotope, unless the isotope has both an even number of protons and an even number of neutrons. The nuclei of many elements, such as 13 C, spin generating a magnetic field.

http://ups.edu/faculty/hanson/Spectroscopy/NMR/CNMR.htm WebNMR spectroscopy is an analytical technique used to identify and find the structure of different molecules. Carbon-13 NMR detects the chemical shift value of the carbon isomer carbon-13. Chemical shift is related to magnetic resonance frequency. Carbon-13 nuclei show resonance because they have an odd mass number, meaning they have spin.
