How do 12c and 13c differ

WebBoth 12 C and 13 C are called stable isotopes since they do not decay into other forms or elements over time. The rare carbon-14 ( 14 C) isotope contains eight neutrons in its … WebThe 12 C isotope of carbon - which accounts for up about 99% of the carbons in organic molecules - does not have a nuclear magnetic moment, and thus is NMR-inactive. Fortunately for organic chemists, however, the 13 C isotope, which accounts for most of the remaining 1% of carbon atoms in nature, has a magnetic moment just like protons.
