C2H4Br2 CH3CHBr2 C-13 nmr spectrum of 1,1-dibromoethane analysis of chemical shifts ppm interpretation of 13C chemical shifts ppm of 1,1-dibromoethane C13 13-C nmr 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 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 - 1,1-dibromoethane here.

Interpreting the C-13 NMR spectrum of 1,1-dibromoethane

As you can see from the diagram above there are 2 different chemical shift lines in the C-13 NMR spectrum of 1,1-dibromoethane indicating 2 different chemical environments of the 2 carbon atoms of 1,1-dibromoethane.
