We confirm graphene oxide, a two-dimensional carbon structure at the nanoscale level can be a strong candidate for high-efficient interconnector in radio-frequency range. In this paper, we investigate high frequency characteristics of graphene oxide in range of 0.5–40 GHz. Radio-frequency transmission properties were extracted as S-parameters to determine the intrinsic ac transmission of graphene sheets, such as the impedance variation dependence on frequency. The impedance and resistance of graphene sheets drastically decrease as frequency increases. This result confirms graphene oxide has high potential for transmitting signals at gigahertz ranges.
finding the resonance frequency of substances is apparently a VERY VERY difficult
It depends on molecule structure. More complex substance, more oscillation axis, more resonant frequencies. So, most substances have many resonant frequencies, not one, and it is more common to talk about "vibrational spectrum", instead of "resonant frequency". So, use "vibrational spectrum of ..." to find what you want.
"Resonant frequency" is rarely used in literature like that. What you want is microwave spectroscopic data and the peaks shown in the spectrum are the resonant frequencies
Graphene oxide forms crystals with a 2.1 nm structure, there's a band there to detect but it's at a very high frequency above visible light. A simple resistance test is more doable, if someone is more conductive they have something in them, it's just non-specific as to what is conductive. It's not really safe to aim an x-ray spectroscopy gun at someone, so you'd need samples anyway.

You could probably speed this up by examining harmonic bands then narrowing in on bands where you observe small changes in temp

You might find in healing use of gemstone, crystals, minerals books, such as the Crystal Bible
