@Brian_BH I noticed that the Extra section is taken out. Does that usually happen when you add new tags? I know the same case has been for past suggestions, so just wanted to see if there’s any way we can help with avoiding this Extra section from being taken out from your future suggestions with changed tags.
Also, I know you referenced QID 400990 here. Are the other tags also relevant? If so, could you provide a rationale for each?
Yep. 
Weird; I’ll keep an eye on the extra field. It’s definitely not anything I was intending to do. Maybe some keystroke habit? I’ll keep a watchful and try to avoid nicking it in the future.
403494: requires H NMR knowledge sufficient to be able to predict the splitting of a given protein, requiring the knowledge of NMR in general and the n+1 rule more specifically, in order to select a proper choice option for potential splitting (singlet, doublet, triplet, etc.).
400990: I just put a few minutes ago and I believe had a rational included, but: requires knowledge and familiarity with the effects of shielding necessary to predict the effect (and direction) of shielding on a proton displayed in an H NMR; specifically requires knowing that more shielded protons will appear nearer in the field (less downfield), as the answer option choices are intentionally mixed so as to discriminate the knowledge of shielding-versus-relative-downfield position.
401694: Similarly, this question requires being able to explicitly predict which protons present in an example molecule would appear as a doublet on an H NMR spectrum; requiring the n+1 (as well as shielding) knowledge to differentiate, and discriminate, from other answer options.
401243: Given an example molecule (in this case ethyl acetate) the question asks to predict which, of various example NMR peaks, would most likely correlate to the protons present in ethyl acetate. Requires understanding both n+1 as well as relative shielding/downfield position, in order to discriminate from less plausible/likely answer options.
403495: Given an example compound (adamantine), the question asks to predict the expected chemical shift, in ppm, of the protons present in the molecule. Requires the understanding that, given the example molecule is very very shielded, that the resulting chemical shift would be small relative to other answer options, given the effect of shielding on downfield placement in a chemical shift.
4400504: Requires the understanding of integration relative to proton number, with the question asking to discriminate for a given integration (greater than 1), which of a series of example molecules could be the likely indicated. Requires understanding that integration correlates with proton number, and that all things being equal a lower number of equivalent protons, relative to nearby electronegative atoms, would lead to greater deshielding and (owing to the single proton) a smaller integration value.
No worries. And thank you for these detailed rationales! I found a way on our end as maintainers to revert edits for the Extra section. So, honestly no worries at all about this. As always, thank you for all your contributions! They’re much appreciated
In terms of the tags, since this note is about how shielding affects where a peak is in the field, I think it wouldn’t be directly relevant to 403494. What are your thoughts on that specific nid?
It’s a fair point. 404494 is more tightly focused on splitting, as opposed to shielding/deshielding. I’m happy to keep relevant tag suggestions to more tightly constrained cards, that more directly touch on the core concept being tested.
I think this one was still one of my old batches, where I hadn’t dialed in my workflow quite as much as I have now (hence there are still some floating around that may not have rationales, etc.). But the last several days I’ve been much more diligent and focused about it, so onwards and upwards I hope.
I always forgot something in my replies - sorry, I have one more thing I wanted to ask: I noticed your last rationale was for QID 4400504. Was this meant for 401242?
Ah, yes. The last one on the bottom of the right-most column. Correct.
