Normalized intensity for the first 4H losses in PAHs with a single type of peripheral hydrogens. Panel a: Triphenylene (), with only quarto hydrogens connected by bay-regions; panel b: perylene (), with only trio hydrogens, also connected by bay-regions; panel c: coronene (), with only duo hydrogens connected through tertiary carbons; panel d: hexabenzocoronene (), containing only trio hydrogens connected by bay-regions. In black is shown the intensity of the corresponding parent molecule, while in blue, red, green and yellow are displayed the fragments corresponding to one, two, three and four hydrogen losses respectively.
