Show more >The transformation of molecular precursors in the gas phase into nanoparticles in the condensed phase (soot inception) during combustion has not yet been fully understood. While several hypotheses on soot inception are currently being examined, their validation requires detailed knowledge of the physical–chemical properties of the matter first formed in the condensed phase (incipient soot). However, characterizing short–lived species in a reactive environment at high temperature is inherently difficult. In this work, we propose a multi–analytical approach to indirectly characterize chemical composition and structure of incipient soot obtained in controlled laboratory conditions. The results are explained in light of recent developments on the characterization of the optical and magnetic properties of incipient soot, and used to build a phenomenological model of soot inception. The acquired information is key to support the hypothesis selection and to understand the reactivity of combustion byproducts and thus their impact on health and the environment.Show less >
