Amide N-H Stretching Vibrations

For primary amides, two sharp bands of medium intensity are observed due to the asymmetric and symmetric stretching vibrations. In dilute, non-polar 

Cis- form (in dilute solution) 3440-3300 2.91-3.03 m m-w N-H str. cis- form remains mainly association 

Hydroxamic acids (solid phase). 3300-2800 3.03-3.57 w-m m-w Three bands, N-H str and O-H str 

Oxamides. thioamides, amides of n-fatty acids, polyamides, phosphonamides, polyglycines,and numerous other related compounds have been studied.
