Differences observed in the IR and NMR spectra of ( E ) -stilbene and meso-stilbene dibromideshould be discussed. Concept introduction: Infrared absorption frequencies values are given as follows: The area within each peak corresponds to the number of equivalent protons found at that chemical shift values. Spin-spin splitting is observed as a result of the interaction amongst non-equivalent NMR active nuclei. This is independent of the strength of the external magnetic field. The formula to calculate the number of peaks in the 1 H NMR spectra is as follows: Number of peaks = N + 1 Where, N is the number of equivalent protons on the adjacent carbon atoms.
