Infrared (IR) and/or Nuclear Magnetic Resonance (NMR) carbon-13 data are presented for 3-x and 4-x substituted anilines. Correlations are presented for the δ13C-1 chemical shift vs. Hammett δp and δm values, vasym., NH2 vs. δ13C-1, vsym. NH2 vs. δ13C-1, δ13C-1 vs. vasym. NH2, δ13C-1 vs. the absorbance ratio A(vasym. NH2/A(vsym. NH2), and δ13C-l vs. Taft δR°. The IR data for these compounds are recorded in the vapor phase, and in hexane, carbon tetrachloride, and chloroform solutions. The NMR chemical shift data for these compounds in solution with chloroform were obtained with the use of tetramethylsilane as the δ13C resonance reference frequency.
