In a (^{13}\text{C})-NMR spectrum, spin–spin splitting due to (^{13}\text{C}–^{13}\text{C}) coupling is generally not observed because of the extremely low natural abundance of the (^{13}\text{C}) isotope. Carbon exists predominantly as (^{12}\text{C}), which has nuclear spin zero and is therefore NMR inactive, while (^{13}\text{C}) has a nuclear spin of ( \tfrac{1}{2} ) and occurs with
