aniline ir spectrum

Maghnite

aniline in the presence of sulfuric acid using potassium persulfate (PPS) as oxidant Using molar ratio of monomer to oxidant of 2:1 the aniline was polymerized and largely incorporated into the Maghnite which was confirmed by FTIR 1H-NMR spectra and UV-Vis spectroscopy These methods show the shifting of some peaks which indicate the formation of some new bonds and support the

IR Spectroscopy Tutorial: Amines

The spectrum of aniline is shown below This primary amine shows two N–H stretches (3442 3360) note the shoulder band which is an overtone of the N–H bending vibration The C–N stretch appears at 1281 rather than at lower wavenumbers because aniline is
