^ I had a suspicion that that may be the case, they were received from different people though.
I had been told that a lot of NMR reports do look similar and hadn't checked thoroughly to see if it was identical.
each NMR machine and each NMR run is unique they all run at slightly different frequencies and have different locks and tunes and probes they also use slightly different solvents, it is easy to see it if you know.
even the same sample run on different machines will give very slightly different results because each machine has a slightly different magnetic field and therefore slightly different peak shape. the peaks however will be in the same place and be the same relative size.
in the above case you don't even need to be that clever, there is a distinctive double peak on the very upfield end right end of the spectrum probably because the NMR operator was clueless, one is probably TMS though why it was eccessary to use TMS as a internal lock is beyond me.
we have the same NMR analysis being presented as different things, the whole thing is just bullshit.
the same applies to the original NMR, that is a sample where we don't know if the sample is representative of the bulk material and additionally is an NMR supplied by somene with a vested commercial interest in the substance.
this whole 6-ABP thing is a complete farce, there are no such things as official vendors of RC's despite what certain people (who perhaps have ulterior motives) seem to want to suggest, they are all unofficial, all irresponsible, all shady and all illegal. There is no quality control, no toxicology and it is just bad.
