We found a Raman peak in the silver powder around 1000 cm-1. What could be the origin of this peak?

As we know, for Raman spectroscopy, a change in dielectric constant is required w.r.t. phonons, which does not apply to metals. Therefore, pure metals are Raman inactive. Also, this 1000 cm-1 peak...
