WebThe coupling constant, J (usually in frequency units, Hz) is a measure of the interaction between a pair of protons. In a vicinal system of the general type, Ha-C-C-Hb then the coupling of Ha with Hb, J ab , MUST BE EQUAL to the coupling of Hb with Ha, J ba, therefore J ab = J ba . The implications are that the spacing between the lines in the ...
