The IR spectrum of aniline exhibits characteristic peaks associated with its functional groups. The N-H stretching vibration is observed around 3400 cm-1, while the C-H stretching vibrations appear in the region of 3000-3100 cm-1. The aromatic C-C stretching vibrations are prominent around 1600 cm-1, and the C-N stretching vibration is typically found near 1300 cm-1. These characteristic peaks enable the identification of aniline and provide insights into its molecular structure and bonding.
