VUV photoprocessing kinetic curves of MeCor⁺ and its fragments. (a) Normalized intensity of each channel (defined by Eq. (1)) for VUV irradiation times up to 1000 s. Top panel: main channels Bottom panel: zoom on the minor channels. The solid curves correspond to the fitting functions that were derived with the procedure described in Sect. 2.4. (b) Normalized-to-one kinetic signal of each ion channel.
