Black carbon (BC) significantly influences climate change through light absorption. Traditional emission inventories equate BC with elemental (EC) and overlook the variability in its properties across sources, leading to uncertainties predictions. This study shows that EC from solid fuel combustion contains substantial low-maturity (char), whose emissions increase alongside absorption of soluble organic (OC) as aromaticity rises. Concurrently, abundance oxygenated polycyclic aromatic hydrocarbons (O-PAHs) OC also increases. suggests char brown (BrC) share similar formation pathways O-PAHs key precursors. Time-resolved analysis during cycles revealed a significant positive correlation between O-PAHs, OC, emissions, further supporting this shared pathway. The nonbonding orbitals BrC facilitate n → π* transitions visible region, which are more wavelength-dependent than π transition high-maturity (soot). highlights light-absorbing intermediate, influencing emitted combustion. These insights into optical carbonaceous aerosols enhance our understanding their impacts underscore need differentiate soot models improve accuracy.
