Five vs. six membered-ring PAH products from reaction of o-methylphenyl radical and two C₃H₄ isomers

Abstract

Gas-phase reactions of the o-methylphenyl (o-CH3C6H4) radical with the C3H4 isomers allene (H2C=C=CH2) and propyne (HCºC-CH3) are studied at 600 K and 4 Torr (533 Pa) using VUV synchrotron photoionisation mass spectrometry,...
