Temperature effect on decay of ions in a plastic crystal as studied by pulse radiolysis and γ radiolysis: 2,3- dimethylbutane

Abstract The decay-rate constants k of dipentyl disulfide anions in 2,3-dimethylbutane (2,3DMB) were measured over a temperature range of 100–140 K by pulse- and γ-radiolysis methods. The decay-rate constants could be varied as much as nine orders of magnitude. Solid 2,3DMB has two crystalline phases; crystal-I (136–145 K) and crystal-II (
