Reply to comment by seriousnotshirley in Is NaCl relatively common in the galaxy/universe? by PHealthy

Huh, I hadn't heard of that, but that's super interesting if so. I don't see any mention of NaCl in https://ui.adsabs.harvard.edu/abs/2014ApJ...787..112C/abstract or the other HEXOS papers, but I'm just doing a ctrl-f, so it's possible I missed it (if they specified the isotopologue, for example)

It was 15 years ago so I probably mis-remembered it. My chem professor did a lot of rotational spectroscopy and had invited someone from HEXOS to give a presentation.

I know the stuff I looked at at room temp looked like a bunch of noise. I tried writing some algorithms to help fix parameters of the molecule to match observed spectra and it went badly above something like 50 K. I'm surprised you were able to pick out transitions near a star! Nice work.
