This is a very interesting paper tackling an important aspect of atmospheric chemistry.
I would like to draw the authors' attentiion to our paper on isoprene oxidation coupled with manganese catalyzed autoxidation of sulfite (1), which is matching section 4.4 . That paper shows the influence of acitidy on the rate of autoxidation and on the rate of isoprene conversion based on experimental observation and detailed kinetic modelling. The kinetic model used includes autoxidation of Mn(II), autoxidation of S(IV) catalyzed by Mn and oxidation of isoprene. It explains the observed influence of pH on the reactions (with and without isoprene present) better than empirical rate equaitions shown in section 4.4.
Our another paper (2) describes the aqueous-phase transformation of isorene in the presence of HONO. Also in this case the acidity of solutions had significant effect on the isoprene conversion demonstrated by experiments and explained by a model. However, in this case the role of acidity was simple - conversion of isoprene required undissociated HONO present.
The authors might consider using the quoted papers as a minor illustration to their valuable lecture.
with best regards
