QUESTION
NH absorptions are usually much weaker and less broad than the OH absorptions.
NH absorptions are usually much weaker and less broad than the OH absorptions. Neat, aliphatic, primary amines show two absorptions between 3400 to 3330 cm-1 and 3330 to 3250 cm-1 due respectively to asymmetrical and symmetrical stretch. Stretch at 3300 cm-1. Why do tertiary amines not absorb in this region of the spectrum?
