WebMar 6, 2014 · In summary, integration of 13 C NMR spectra acquired with short relaxation delays is a convenient method for determination of compound ratios, and it complements other commonly used techniques, particularly in cases when these techniques are insufficient. 13 C NMR integration employing short D1 values affords a greater spectral … WebNMR spectroscopy commonly used for compound analysis is 1 H-NMR and 13 C-NMR. Techniques can be used to determine the structure conformation, the number of protons, and the number of carbons in the structure of a chemical compound. So far, there have been many publications related to the use of this spectroscopic technique. However, the steps ...
