electron-hole pair damping of vibration, thin film resistivity

vst98

Hello,
I'm reading something about adsorbate induced surface resistivity changes in thin metal films
and there is often mentioning of electron-hole pair damping, as for example:
"electron-hole pair damping of the parallel(to the surface of thin film) frustrated vibration of the adsorbate(molecules/atoms) ... "

I don't understand what this means clearly, is it that vibration of the adsorbate decays
by producing e-h pairs in the thin film ? But why would that happen ?
Also what is meant by frustrated vibration, what frustrated means in this context ?
