C Nmr Spectrum Table

C Nmr Spectrum Table. A table of typical chemical shifts in C13 NMR spectra carbon environment chemical shift (ppm) C=O (in ketones) 205 220 C=O (in aldehydes) 190 200 C=O (in acids and esters) 160 185 C in aromatic rings 125 150 C=C (in.

For carbon element the most abundant isotope 12 C (with ~99% natural abundance) does not have a nuclear magnetic moment and thus is NMRinactive The C NMR is therefore based on the 13 C isotope that accounts for about 1% of carbon atoms in nature and has a magnetic dipole moment just like a proton The theories we have learned about 1 H NMR spectroscopy also.
