A smaller absorption near 3200 cm -1 (shaded orange in the spectra) is considered to be the result of interaction between an overtone of the 1600 cm -1 band with the symmetric N-H stretching band.

Tertiary amines have no absorption in this region because they have no N–H bonds. Hydrogens on the carbon next to nitrogen are deshielded because of the electron-withdrawing effect of the nitrogen, and they therefore absorb further downfield than alkane hydrogens.
