Main reaction routes in the second and third stages of φ = 5.
ACEPHA (acephenanthrene). Fluoranthene (FLTHN) is then formed mainly from
an intramolecular rearrangement reaction (R95) from ACEPHA and partly through
combination of C

(R84).
From fluoranthene, H abstraction (R155) and C
2
addition (R235) give BGHIF
(benzo[ghi]fluoranthene). Further H abstraction (R157) and C
2
addition (R236) lead
to COR (corannulene). COR can decompose into CPCDPYR (cyclopenta[cd]pyrene)
through reaction with H (-R109, R106).
In parallel with the above reactions, in the third stage phenyl and benzene
combine themselves to form CZ

(bi-phenyl) through R322. H abstraction
(R323) and C
2
addition (R325) form A3(phenanthrene). Further H abstraction (R101)
and C
2
addition (R102) give PYRENE. Reactions of the third stage proceed with
rates about a tenth of those proceeding at the second stage but they last for more
than 10 s and lead to the broad temporal species profiles seen in
Figures 2.67
Larger species also form, but their production rates are small and not analyzed
here. Benzene and indene have concentration profiles peaking early and decreasing
later. Richter's calculation results on a flat flame failed to reproduce the indene
