A peak at approximately 178 ppm in the C13 spectra is characteristic of the ester functional group of carbonyl compounds.
What is C13 NMR spectroscopy?
C13 NMR spectroscopy is a form of nuclear magnetic resonance spectroscopy using the C13 isotope.
The standard used in 13C-NMR spectroscopy to define the 0 ppm point is tetramethylsilane (TMS).
Each peak obtained in the C13 spectra correspond to a given funnmctional group.
