The resonance Raman effect was applied to the measurements of spectra of aromatic amines. The aromatic amines must be derivatized beforehand to colored compounds which fulfil the resonance Raman conditions, because the amines hardly have the absorption bands in the visible region. Two derivatizing reagents (2,4-dinitrobenzaldehyde and pdimethylaminobenzaldehyde) were used to make colored compounds. The Schiff's base type derivatives exhibit the absorption maximum at 356-512nm. The derivatives gave the pre-resonance Raman spectra. Although the derivatives of aromatic amines gave in general similar resonance Raman spectra, they could be distingnished by comparing the patterns of the spectra in 800-1800cm^<-1> region. The closer absorption bands to the wavelength of excitation laser line and larger molar absorptivity of the derivatives, resonance Raman band intensity was increased.
