Demonstrated redistribution within the orientational distribution under varying potentials

Abstract

The microscopic meaning of the point of zero charge at the Pt(111)/pure-water interface remains unresolved because interfacial water has often been described through selected structural descriptions rather than through a statistical-mechanical distribution.Here, we examine whether the point of zero charge is associated with the emergence of a distinct new interfacial-water structure or with redistribution within an orientational distribution that remains occupied over the applied-potential DOI: 10.
