I How to obtain the resonance frequencies of a given material?

[Andre Teixeira]

The frequency of plasma already achieved ... in a study, is presented the resonance frequency in eV, how to obtain in Hz? Wo = 7eV

Welcome to the PF.

Can you provide a lot more context to your question and more details? What was the experimental setup?

 

[Andre Teixeira]

Basically, my study is to draw a permissivity curve by frequency, using the Lorentz oscillator, I need some parameters, such as plasma frequency and resonance frequency of the material, I can not find in the literature the frequency of resonance of the PET material

Resonance at audio ? RF ? what ? ( I'm assuming RF)
and please confirm what you mean by PET material ?
the mechanical resonance ( sound wave) of a block of material will depend on things like its size, shape, density, temperature etc

Do you mean permitttivity rather than permissivity? Look up the definitions. You may find this link useful chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/https://ocw.mit.edu/courses/electri...-spring-2011/readings/MIT6_007S11_lorentz.pdf

PET, Polyethylene terephthalate, I want to know how to obtain the parameters of the lorentz oscillator, for this material, PET, a material that requires an extra complexity not to be pure, like gold or aluminum

Sorry for bad English.
