So what symbol are you talking about that looks like the Ammonia molecule? I don't see it in the main spectrogram, and I haven't been following this thread closely...
The lines in the central diagram, being the sphere the main molecule and looking at the lines as depicted in the image I posted as well.

I'm not saying this was a clue from the spectrogram, I said it raised my hype and I decided to give it a go, but was just pure guessing, or luck, whatever you want to call it.
