The Ultraviolet Absorption Spectra of Hydrazones of Aromatic Aldehydes RICHARD L. HINMANI

Received March 7, 1960 Ultraviolet absorption spectra are reported for a variety of hydrazones of benzaldehyde, substituted both on the terminal nitrogen and in the ring. The spectral features accord with the sugpestion that the hydrazone group (>C=N-NC=iY-N
