Click on any peak for help in interpreting this spectrum.
The peak is a triplet, indicating that it corresponds to a CH2. The chemical shift (d 80) suggests that the CH2 is adjacent to an electron-withdrawing group, such as an oxygen, and may be further shifted due to steric effects.
The peak is a quartet, indicating that it corresponds to a CH3 group. The chemical shift (d 54) suggests that the CH3 is adjacent to an electronegative atom (i.e., oxygen). Note that there are only two peaks in the spectrum, but there are four carbons in the molecular formula.

C4H10O2
From the molecular formula, the compound has "0 degrees of unsaturation" (no double bonds or rings).
IUPAC Name: 1,2-dimethoxyethane
The 13C NMR has two peaks, a quartet at d 54 (a CH3) and a triplet at d 80 (a CH2). Since the molecule has four carbons and only two 13C NMR peaks, there must be symmetry. Both peaks are in the regions where carbons next to electronegative atoms occur (oxygen).
