How many NMR signals does #CH_3CH_3# show?
Ethane's H NMR spectra displays a single signal.
Since there are numerous symmetry elements in the molecule, the two carbon atoms stand for a single hydrogen environment.
Spin-spin splitting does not occur because equivalent protons do not split apart.
About δ 0.9, we should observe a single, sharp peak.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
