WebJul 13, 2016 · Isotope shifts, including deuterium-induced 13 C NMR isotope shift, have been studied and used since early in the development of NMR. The majority of publications in this field have been focused on the analysis of the isotope chemical shift values rather than evaluating the intensities of the various 13 C resonances of the different isotopologues.
