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 resonances, called chemical shifts, are measured with respect to the TMS, and depend on the individual (electronic) chemical environment of the 13C atoms in an organic molecule - methyl ethanoate here.

Interpreting the C-13 NMR spectrum of methyl ethanoate

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

CH3COOCH3

(Note the 3 different colours indicating the 3 different chemical environments of the 3 carbon atoms in methyl ethanoate).

13C chemical shifts (a) to (c) on the C-13 NMR spectrum diagram for methyl ethanoate.

The carbon-13 NMR spectra provides direct evidence of 3 different carbon atom environments for the 3 carbon atoms in the methyl ethanoate molecule, deduced from the presence of 3 different 13C NMR chemical shifts (ppm).
