They don't mention it in the article, but it's likely to be IR spectroscopy, since that can measure resonance of H2O molecular bonds, which would be specific to symmetries/energies in Ice-7 and very different from the known spectrum of diamond.

However, I suppose it could also be X-ray crystallography, which would measure the actual crystal structure. Probably other methods as well...
- creep 9y agoThey do mention it in the article >But while they were scanning the diamonds with high intensity X-rays, they saw something else: The first conclusive evidence of ice-VII on the planet. But probably they used other methods to confirm.
- mcherm 9y agoBut of course, since ice IX is fictional, we don't know what it's IR spectrum or X-ray crystallography pattern is...
