Abstract

Abstract: One-electron reduction of 1-(4-biphenylyl)-w-haloalkane (BPx-n) by solvated electrons and the intramolecular reactions of the radical anion thus formed have been investigated using the pulse-radiolysis technique. The spectrum observed immediately after the pulse has an absorption maximum at 410 nm which is assigned to the corresponding biphenyl radical anion. The decay behavior of all these 410-nm bands follows first-order ...
