Recently I worked out a way to solve AB patterns in a more time-efficient manner using Excel. The Hans Reich collection gives several suggestions on reporting the data, two of which are shown below.
2.63, 2.69 (ABq, 2H, JAB = 12.2 Hz)
2.66 (ABq, 2H, ΔδAB = 0.05, JAB = 12.2 Hz)
Is there one way which is used more than any other ways?
