Question

Suppose Ha, couples to Hb, Hc, and Hd. If Jab>Jac>Jad, then the multiple for Ha will appear as eight peaks, as shown by the tree diagram. 

Suppose Jac ~= 1/2 Jab andJac ~= Jad. Sketch the corresponding tree diagram. Number the peaks from left to right. List all pairs of peaks to subtract to obtain each J value.
