From: Hydrogen migration in inner-shell ionized halogenated cyclic hydrocarbons
Mass spectra of (a) BCpro, (b) BCbut, and (c) BCpen irradiated at 140Â eV (red) and 315Â eV (black) photon energy, normalized to have the same integral counts. The mass spectra have no significant peak beyond 90 amu except for two small peaks corresponding to the parent ion, shown in the zoomed-in view on the right.
