Proton magnetic resonance spectrum of 25% (volume) methyl 2,3-dubromopropionate in benzene exhibits a typical ABC patter in which the four strong lines from each nucleus can be immediately recognized. The assignment of spectral lines and the determination of energy-level diagram were thus straightforward.
Field-sweep spin decoupling experiment with respect to the other transition-square (with B spin kept at －1/2) of the sample was found to be in complete analogy with two-spin AX system. However, spin decoupling with respect to the inner transition-square (with B spin kept at ＋1/2) reveals a weak satellite line on each side of the decoupled A (or C) signal. These weak satellite lines are found to be due to JAB (or JBC) and may prove to be useful for the direct determination of JAB and JBC. - 英文摘要： --
