Identification of Raman defect lines as signatures of ring structures in vitreous silica

Alfredo Pasquarello, Roberto Car

By analyzing the vibrational eigenmodes of a model structure obtained previously by quantum molecular dynamics, the two sharp features appearing in the Raman spectrum of vitreous silica could conclusively be assigned to three- and four-membered ring struct ...
