This is suspicious because you should be able to include the digital version of the NMR file, which is much harder to “alter” and would be regarded as much trustworthy than a blurry printout. In this case it does seem as if this was not simply an honest mistake but more likely a desperate attempt to please a demanding advisor. The graduate school community should definitely sit down and re-evaluate how much pressure is acceptable to put on the students. If you tell them: “Either you get this compound or you will never graduate” something will eventually give and, in some instances, what gives is the ethics of the scientist under pressure.

I think they are overreacting, everybody, including the scientists, is prone to making a mistake, if anything, they were simply a little sloppy. I have encountered similar situations in my research, were the NMR looks as if I got the compound that I was expecting and other analysis techniques give you ambiguous results. Fortunately in all these cases I have caught the mistakes because my compounds did not react as I was expecting them to or the NMR started to look “funny” after an extra round of purification. My point is that this looks like an honest mistake although we would have to read his thesis to find out if he simply misinterpreted his data or if he intentionally concealed the results indicating that the synthesis was not yielding the expecting products. If the whole thesis was based on the system which does not work, then his degree should be reevaluated (because this would mean he was “sloppy” during several years). However, if this merely constituted a chapter or a section of the dissertation then it was an honest mistake which could happen to anyone who is too eager to publish.
