  "abstract": "The short-range to mid-range structure of inorganic glasses profoundly impacts their physical properties. In this work, we have used multiple spectroscopic methods to examine the change in the network structure of amorphous silica with addition of Cl. Unlike analogous F-doped silicas, where the bonding of halogen leads to terminal Si-F groups, NMR and Raman data for Cl-doped v-SiO2 indicate bridging between silica tetrahedra, preserving rather than reducing network connectivity and contributing to their elastic stiffness and viscosity behaviors. These bridging Cl atoms make v-SiO2 stiffer while having the same effect on density behavior per mol % dopant as F in v-SiO2 and thus may be a desirable attribute in tailoring v-SiO2 for optical applications.",
