A Radical Post‐Scavenging Study of Irradiated Cyclic Hydrocarbons in the Solid State

Abstract

Cycloalkanes were irradiated in the solid phase at 77 K. Post‐irradiation scavenging of radicals by dissolving the irradiated cycloalkane at low temperature (100 ‐ 165 K) in a propane‐oxygen mixture lowers the dicycloalkyl and cycloalkene G values to an extent of 35‐55%. From the Δ G decrease values, we propose that the trapped radical G values be 3.1, 2.7 and 2.7 at 77 K for cyclopentyl, cyclohexyl and cycloheptyl radicals, respectively.
