The present invention relates to a method for analyzing the length of sulfur crosslinking bonds in a vulcanized rubber using NMR spectrum. In some embodiments, the method comprises obtaining, independently, a carbon-13 nuclear magnetic resonance (C NMR) spectrum of a standard substance, wherein the standard substance containing carbon atoms, and aC NMR spectrum of the vulcanized rubber, wherein theC NMR spectrum of the standard substance and theC NMR spectrum of the vulcanized rubber are obtained under the same conditions; obtaining, independently, free induction decay (FID) amplification values of characteristic peaks in theC NMR spectrum of the standard substance, and FID amplification values of characteristic peaks in theC NMR spectrum of the vulcanized rubber; and measuring the length of sulfur crosslinking bonds in the vulcanized rubber.
