Signature of small rings in the Raman spectra of normal and compressed amorphous silica: A combined classical and ab initio study

Abdelali Rahmani, Magali Benoit, Claude Benoit

We calculate the parallel (VV) and perpendicular (VH) polarized Raman spectra of amorphous silica. Model SiO2 glasses, uncompressed and compressed, were generated by a combination…
