dc.description.abstract	To aid in understanding black carbon (BC) formation during smoldering combustion in forest ﬁres, we characterized charring of a softwood and hardwood. Charring (150, 340, 480°C) caused mass loss (7–84%), enrichment of organic carbon (OC) (0–32%), and 13C depletion (>150°C). As determined by 13C MASNMR, the OC composition of the woods was dominated by (di)-O-alkyl structures, and the chars by alkyl and aromatic structures. With increasing temperature, aromatic structures increased and the chars became more similar, although initial diﬀerences in OC concentration and d13C of woods persisted. The BC cluster sizes apparently remained small, pointing towards a low resistance against oxidation.	ru_RU
