Web10 apr. 2024 · We also know that the detection sensitivity of 1H is 5870 times 13C, due to the natural abundance of 13C being very low, only 1.1%, and the small magnetogyric ratio of 13C.45 Therefore, the sensitivity of ESR is much larger than that of the 13C NMR. Thus, even if the signal of 13C NMR may not be detected when the population of carbon …
