The eleven ion vinyl phosphonic acid (VPA) molecule consists of a phos-
phorus ion that serves as a cationic anchor for two electron-rich functional
groups, viz., a tripodal oxygen-rich base and vinyl hydrocarbon tail. Recent
inelastic tunneling experiments have implied that VPA binds in a tridentate
coordination though its base leaving the vinyl tail free to react with a resin
