The 13C NMR chem. shifts were used to predict the Z and E configurations of 13 di-and trisubstituted ethylenes including 4, 4-dimethyl-2-pentene, 2, 2-dimethyl-3-hexene, and 2, 4-hexadiene. The Z ethylenes had aC signals at higher fields relative to 13CS2 than the aC of the corresponding E ethylenes.[on SciFinder (R)]
