APPLICATIONS OF 13C NMR CMR is a noninvasive and nondestructive method,i.e,especially used in repetitive In-vivo analysis of the sample without harming the tissues . CMR, chemical shift range(0-240 ppm) is wider compared to H-NMR(0-14 ppm), which permits easy separation and identification of chemically closely related metabolites. C-13 enrichment, which the signal intensities and helps in Fluorine-19 nuclear magnetic resonance spectroscopy (fluorine NMR or 19 F NMR) is an analytical technique used to detect and identify fluorine-containing compounds. 19 F is an important nucleus for NMR spectroscopy because of its receptivity and large chemical shift dispersion, which is greater than that for proton nuclear magnetic resonance spectroscopy.

In the nmr spectrum of the dianion, the innermost methylene protons (red) give an nmr signal at +22.2 ppm, the adjacent methylene protons (blue) give a signal at +12.6 ppm, and the methyl protons (green) a signal at +5.6 ppm.

So the peak corresponding to 1.0 ppm is due to methyl protons. That’s about the easy way of interlinking the concept to remember NMR spectrum table with both logic and reasoning.

This material has several disadvan-tages, however: it is not volatile, so it cannot be readily eliminated ifthe sample has tobe recovered. In addition, unless one purchases it in the relatively expensive deuterated form, it adds three more signals to the spectrum (methylenes 1, 2, and 3 appear at 2.91, 1.76, and 0.63 ppm The 13 C NMR spectrum for but-3-en-2-one.
