My post addressed only the misapplication of NMR to MFD. I don't doubt that there are other ways to detect distant compositions. Ferinstance, spectroscopy is used in astronomy to analyze the composition of stars and interstellar gasses, but this method requires light transmission through the object.

I think seriously in other kind of frequency, the based on vibration of the molecules of each element, very precisse for each.

Molecular vibration is dominated by NMR. Water molecules vibrate at the NMR frequency of hydrogen. Besides, objects like gold & diamonds are not molecular compounds, but rather atomic structures that have metallic or covalent bonding structures. So claiming that their "molecules" vibrate is meaningless.
