Splitting of peaks in NMR spectra arises due to the coupling of closely related protons. The coupling constant decides that how much coupling is happening the two protons, higher the tendency of the proton to couple, higher will be the value of coupling constant value.For substituted alkene such as styrene, there are trans coupling, cis coupling and geminal coupling. The order of the coupling constant is :- Trans coupling (11 to 19Hz) > Cis coupling (5 to 14Hz) > Geminal coupling (0 to 5Hz) The splitting tree for Hc in styrene can be shown as: The chemical shift value is taken from the NMR plot corresponding to Hc and the coupling constant value are decided according to the type of coupling. For Hc proton, it will first couple with the Ha proton and show Cis coupling with coupling constant of 11Hz and later that will couple with the Hb proton with coupling constant of 1.4Hz and shows geminal coupling.
