N2 - Methyl‐substituted polycyclic aromatic hydrocarbons (PAH) are shown to undergo surface‐catalyzed reactions with oxygen. These reactions generate oxidized products, which include aldehydes, quinones, and anhydrides. The products dominate the O2/N2 negative ion chemical ionization (NICI) mass spectra of methyl‐PAH when the ion source temperature is elevated to 300°C. The NICI mass spectra of methyl‐PAH measured under these conditions show ions that can be used to distinguish the position of methyl groups substituted on fluorene, anthracene, and benz[a]anthracene isomers.
