A GUIDE TO 1H NMR CHEMICAL SHIFT VALUES. Nuclear Magnetic Resonance (NMR) is a commonly used technique for organic compound structure determination. In 1H NMR, applying an external magnetic field causes the nuclei spin to flip.

If a protic deuterated solvent is used (e.g., D2O or CD3OD), then the NH and OH protons will exchange with the deuterium and the peaks will shrink or disappear entirely, since D (2H) does not show up in the 1H NMR spectrum.
1.1 Scope and Organization. The present data collection is intended to serve as an aid in the interpretation of molecular spectra for the elucidation and confirmation of the structure of organic compounds. It consists of reference data, spectra, and empirical correlations from.
In this case, 99% of the time this will represent 3 x CH2. The CH2 groups are all related by symmetry, but there are 3 adjacent H atoms on C. To satisfy this and the symmetry requirement, this usually signifies this kind of grouping : 3 separated CH3-CH2 CH2-CH3 CH2-CH3 groups, still related by symmetry.
