      abstract     = {Secondary organic aerosol (SOA) represents a significant
                      fraction of the tropospheric aerosol and its precursors are
                      volatile organic compounds (VOCs). Anthropogenic VOCs (AVOC)
                      dominate the VOC budget in many urban areas with
                      1,3,5-trimethylbenzene (TMB) being among the most reactive
                      aromatic AVOCs. TMB formed highly oxygenated organic
                      molecules (HOMs) in an NOx-free environment, which could
                      contribute to new particle formation (NPF) depending on
                      oxidation conditions where elevated OH oxidation enhanced
                      particle formation. The experiments were performed in an
                      oxidation flow reactor, the Go:PAM unit, under controlled OH
                      oxidation conditions. By addition of NOx to the system we
                      investigated the effect of NOx on particle formation and on
                      the product distribution. We show that the formation of
                      HOMs, and especially HOM accretion products, strongly varies
                      with NOx conditions. We observe a suppression of HOM and
                      particle formation with increasing NOx/ΔTMB ratio and an
                      increase in the formation of organonitrates (ONs) mostly at
                      the expense of HOM accretion products. We propose reaction
                      mechanisms and pathways that explain the formation and
                      observed product distributions with respect to oxidation
                      conditions. We hypothesise that, based on our findings from
                      TMB oxidation studies, aromatic AVOCs may not contribute
                      significantly to NPF under typical NOx/AVOC conditions found
                      in urban atmospheres.},
