Amine NMR

Propylamine - note the broad and weak NH₂ peak, the degree of coupling, and the shift of the methylene protons due to the electronegative nitrogen

Shifts:

R-N-H: 0.5 - 4 ppm. Variable shifts/broadening for the same reason as alcohols.

Ph-N-H: 3.0 - 5.0 ppm. Deshielded by both anisotropy and resonance.

CH-N: 2.2 - 2.9 ppm

Coupling:

N-H: 50 Hz. Usually not observed. Presumably due to proton exchange.

N-C-H: About 0 Hz. Usually not observed. I'm unsure why. Perhaps due to resonance creating  (+)N=C hence proton exchange..

H-C-N-H: About 0 Hz. Usually not observed. Presumably due to proton exchange.

As with alcohols, adding D₂O to the reaction mixture will cause the NH peak to shrink or vanish.
