Abstract

The radiation damage to Deoxyribose was studied with a view to identify the damaging species. Our results indicate that H, e^-, CO₂-do not cause any appreciable damage in the absence of metal compounds and OH is the sole damaging entity. Iron compounds sensitize very little O₂-damage and CO₂-darnage could not be sensitized. In N₂-saturated solutions metal compounds increase the damage by converting e^- into deleterious OH.
