Amide II and III bands in polyurethane (PU) have been often taken as two of the characteristic bands indicating the formation of urethane structure. Since these bands, however, are very complicated, further studies, especially the effect of H-bonds on amide II and III bands in PU, were ...

amide(ămˈīd), organic compound formed by reaction of an acid chloride, acid anhydride, or ester with an amine. Under strong acidic conditions an amide can be hydrolyzed to yield an amine and a carboxylic acid. The reverse of this process results in the loss of water and is used in...
