C-13 NMR spectroscopy - spectra index

C-13 nmr spectrum of butanone analysis of chemical shifts ppm interpretation of C-13 chemical shifts ppm of 2-butanone butan-2-one doc brown's advanced organic chemistry revision notes 

TMS is the acronym for tetramethylsilane, formula Si(CH3)4, whose 13C atoms are arbitrarily given a chemical shift of 0.0 ppm. This is the 'standard' in 13C NMR spectroscopy and all other 13C shifts, called chemical shifts, depend on the individual (electronic) chemical environment of the 13C atoms in an organic molecule - butanone here.

Interpreting the C-13 NMR spectrum of butanone

As you can see from the diagram above there are 4 chemical shift lines in the C-13 NMR spectrum of butanone indicating 4 different chemical environments of the carbon atoms.

CH3COCH2CH3

(Note the 4 colours indicating the 4 different chemical environment of the carbon atoms in butanone).

The C-13 NMR spectra a provides evidence of 4 different carbon atom environments in the butanone molecule from 4 different chemical shifts (ppm).
