The carbonyl frequency in semicarbazides, semicarbazones, and pyrazolecarboxamides is higher than that in ureas. A phenyl group attached to the third nitrogen atom of semicarbazides lowers the carbonyl frequency. A phenyl group substituted on the first nitrogen atom shifts the carbonyl absorption in semicarbazides to a higher frequency region than do alkyl groups.
