Here we present oxygen near $K$-edge spectra of ${\\mathrm{SiO}}_{2}$ glass to $51\\phantom{\\rule{0.3em}{0ex}}\\mathrm{GPa}$ obtained using x-ray Raman scattering in a diamond-anvil cell. The x-ray Raman spectra below $\\ensuremath{\\sim}10\\phantom{\\rule{0.3em}{0ex}}\\mathrm{GPa}$ are consistent with those of quartz and coesite, whereas the spectra above $\\ensuremath{\\sim}22\\phantom{\\rule{0.3em}{0ex}}\\mathrm{GPa}$ are similar to that of stishovite. This pressure-induced spectral change indicates an electronic bonding transition occurring from a fourfold quartzlike to a sixfold stishovitelike configuration in ${\\mathrm{SiO}}_{2}$ glass between $10\\phantom{\\rule{0.3em}{0ex}}\\mathrm{GPa}$ and $22\\phantom{\\rule{0.3em}{0ex}}\\mathrm{GPa}$. In contrast to the irreversible densification, the electronic bonding transition is reversible upon decompression. The observed reversible bonding transition and irreversible densification call for a coherent understanding of the transformation mechanism in compressed ${\\mathrm{SiO}}_{2}$ glass."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825894100183945","@type":"Researcher","foaf:name":[{"@value":"Jung-Fu Lin"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825894100183939","@type":"Researcher","foaf:name":[{"@value":"Hiroshi Fukui"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825894100183936","@type":"Researcher","foaf:name":[{"@value":"David Prendergast"}]},{"@id":"https://cir.nii.ac.jp/crid/1420564276173729024","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"40303599"},{"@type":"NRID","@value":"1000040303599"},{"@type":"ORCID","@value":"0000-0001-6907-0945"},{"@type":"NRID","@value":"9000006025160"},{"@type":"NRID","@value":"9000107365055"},{"@type":"NRID","@value":"9000411393571"},{"@type":"NRID","@value":"9000388531475"},{"@type":"NRID","@value":"9000398963825"},{"@type":"NRID","@value":"9000009459245"},{"@type":"NRID","@value":"9000262359796"},{"@type":"NRID","@value":"9000413695195"},{"@type":"NRID","@value":"9000409468019"},{"@type":"NRID","@value":"9000412278676"},{"@type":"NRID","@value":"9000018860320"},{"@type":"NRID","@value":"9000107364779"},{"@type":"NRID","@value":"9000283741914"},{"@type":"NRID","@value":"9000415074690"},{"@type":"NRID","@value":"9000258560243"},{"@type":"NRID","@value":"9000402784788"},{"@type":"NRID","@value":"9000258559920"},{"@type":"NRID","@value":"9000237782394"},{"@type":"NRID","@value":"9000397949135"},{"@type":"NRID","@value":"9000415313122"},{"@type":"NRID","@value":"9000009163977"},{"@type":"NRID","@value":"9000413356671"},{"@type":"NRID","@value":"9000412322359"},{"@type":"NRID","@value":"9000396138608"},{"@type":"NRID","@value":"9000396138624"},{"@type":"NRID","@value":"9000415325522"},{"@type":"NRID","@value":"9000015339269"},{"@type":"NRID","@value":"9000016882583"},{"@type":"NRID","@value":"9000410042154"},{"@type":"NRID","@value":"9000239589123"},{"@type":"NRID","@value":"9000411512295"},{"@type":"NRID","@value":"9000283727739"},{"@type":"NRID","@value":"9000401431019"},{"@type":"NRID","@value":"9000347137924"},{"@type":"NRID","@value":"9000258560835"},{"@type":"NRID","@value":"9000018667665"},{"@type":"NRID","@value":"9000413376133"},{"@type":"NRID","@value":"9000243744749"},{"@type":"NRID","@value":"9000391880581"},{"@type":"NRID","@value":"9000258433736"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0056040"}],"foaf:name":[{"@value":"Takuo Okuchi"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825894100183937","@type":"Researcher","foaf:name":[{"@value":"Yong Q.
