Aromatics • Due to the delocalization of electrons in the ring, where the bond order between carbons is 1 %, the stretching frequency for these bonds is slightly lower in energy than normal C=C • These bonds show up as a pair of sharp bands, 1500 (s) & 1600 cm-1 (m), where the lower frequency band is stronger • •C-H bonds off the ring show up similar.to vinyl C-H at 3000- 3100 cm-1 (m)
