The most widely used method for isotope analysis at natural abundance is isotope ratio monitoring by Mass Spectrometry (irm‐MS) which provides bulk isotopic composition in 2H, 13C, 15N, 18O or 34S. However, in the 1980s, the direct access to Site‐specific Natural Isotope Fractionation by Nuclear Magnetic Resonance (SNIF‐NMRTM) was immediately recognized as a powerful technique to authenticate the...
