Open Notebook NMR – the good and the ugly

We've started going through the structures in serial order. Here are two in the first 4 I looked at. One shows near perfect agreement, the other is frankly awful.
Here' s the link to NMRShiftDB: nmrshiftdb2470-1 (solvent: chloroform)

You can see that the RMS is of the order of 1 ppm (we haven't yet calibrated the offset so it's improper to give a clearer figure).
Now here is one that is all over the shop: nmrshiftdb2275-1 (solvent: acetone)

Here is the Additional data on NMRShiftDB:

I have no idea what is going on. Nor has Christoph. So here is your chance to solve the problem. Here are some ideas I suggested

• spectrum and compound got muddled.
• compound is "wrong". I am not clear whether N-SH groups are stable but I don't think they are common.
• there is some serious tautomerism going on.
• this compound disobeys the laws of physics

Anyway you know as much as we do now and you have a link to the entry and the literature. Please add your comments below and if you do discover something fantastic remember where you found the data.
