The infrared spectra of quinoline, isoquinoline, and seven monomethylquinolines were determined. These compounds gave highly characteristic bands in the finger print region of the spectrum, which seem to be useful in the analysis of tar bases. The out-of-plane C-H deformation frequencies could be correlated with their structure in the same way as substituted benzenes or pyridines by separating the quinolines into the componental carbocyclic and heterocyclic rings. The absorption derived from free hydrogens on heterocyclic ring always appeared at a slightly higher frequency than that of comparable methylpyridines. C=C and C=N stretching frequencies showed more complex patterns and the highest band appeared in most cases near 1630 cm^<-1>, whose intensity is particularly variable and appears to have a correlation to the structures.
