A chain mechanism of radiolysis and photolysis in H[AuCl4]-polyvinyl alcohol system

Abstract

A study of optical properties of H[AuCl₄]-containing polyvinyl alcohol (PVA) films allows the basis of a chain mechanism of their photolysis and radiolysis to be put forward. A suggestion is made, that in these chain reactions the Cl radical functions as an active particle, initiating the formation of two interacting chains in reactions of this radical with PVA and [AuCl₄]^- ions correspondingly.
