Comparison of Proton NMR Spectra
of the ortho, meta and para Isomers of Chlorotoluene
The spectra are computer-generated 300 MHz spectra. They come from the Integrated Spectral Data Base System for Organic Compounds. Only the aromatic region is shown (the baseline goes from 6.5 to 8 ppm in each case). The identities of the two substituent groups also affect the appearance of the signal. The doublet of doublets pattern for the para-substituted compound is fairly typical.
