Fig. 4: Inception mechanisms of polycyclic aromatic hydrocarbons in homogenous systems21.
From: Elucidating the polycyclic aromatic hydrocarbons involved in soot inception
The dashed line parallels the physical nucleation limitation line, estimated considering heterodimerization. The orange box represents the temperature and PAH size limitations. The yellow area is the physical nucleation possibility. A6 indicates polycyclic aromatic hydrocarbon contains six benzene rings.
