WebOct 24, 2024 · There are a number of advantages to H − 1 NMR: H − 1 is the naturally-occurring, most-abundant isotope of hydrogen, and is much more abundant than C − 13. The result is that the concentration of H − 1 in a sample is much greater than the concentration of C − 13. It is therefore easier to obtain a spectrum and instruments with a …
