Tutorial Review

A unified approach to mechanistic aspects of photochemical vapor generation

A general model of redox reactions for PVG is proposed, driven by reducing radicals (e(aq), H˙, R˙ and CO2˙) arising from concurrent VUV photolysis of carboxylic acids to yield the nascent elemental species which are subsequently attacked by H˙, H3C˙, H+ and CO to yield volatile products.
