WebH a is trans to H c across the double bond, and splits the H c signal into a doublet with a coupling constant of 3Jac = 17.4 Hz. In addition, each of these H c doublet sub-peaks is split again by H b ( geminal coupling) into two more doublets, each with a much smaller coupling constant of 2Jbc = 1.5 Hz.
