"Notice" is perfect in that context. But I would say "Did you notice," not "Can you notice."
If I say this sentence, it implies that I don't like this odour. I notice "in hell". Is it a negative sentence?
Thank you, coiffe.Roxcyn is exactly right. It's more than negative. It would be closer to exasperation. However, it's obvious nobody would ever say "odoriferous effluence," except maybe a voice in a Monty Python skit. (It's just flamboyant BS.) So if you actually ever heard this, which you wouldn't, you might in fact conclude that the speaker was not at all angry, but just joking around.
Also a point: odoriferous means aromatic, and it means a strong odor -- but not necessarily a bad odor.
So I would say there is ambiguity to the sentence. It's possible to throw "in hell" into a sentence and not be negative -- but it would be more safe to assume negativity.
Thank you, coiffe.
I feel the sense of humour in this sentence.
Very interesting, very fun.
