I’m not sure. I’d guess that the ratio of Deuterium to Hydrogen would produce subtly different wavelengths.
Deuterium is basically Hydrogen, only heavier.
This ratio is how we know that Earth was not seeded with water by the likes of comet CG. So I’d say that the general fingerprint of comets is known, and is taken into account.
I’m not a physicist, but I’d guess If two crossing comets had different wavelengths merging together, I suppose it’s possible that it may have produced an harmonic frequency, making a signal of interest.
