On a heavy path – determining cold plasma-derived short-lived species chemistry using isotopic labelling

Abstract

-sulfonate. The role, origin, and reaction mechanisms of short-lived species, namely hydroxyl radicals, singlet oxygen, and atomic oxygen, are discussed. Interactions of these species both with the target cysteine molecule as well as the interphase and the liquid bulk are taken into consideration to shed light onto several reaction pathways resulting in observed isotopic oxygen incorporation. These studies give valuable insight into underlying plasma-liquid interaction processes and are a first step to understand these interaction processes between the gas and liquid phase on a molecular level.
