Fragmentation of Formic Acid Following Photoexcitation around the Carbon K Edge
Journal of Physics B: Atomic, Molecular and Optical Physics
First page number:
The fragmentation dynamics of core-excited methanoic acid (formic acid) has been studied by means of partial anion- and cation-yield measurements around the C K ionization threshold. All detectable ionic fragments are reported, and significant differences among partial-ion yields are observed. Possible dissociation pathways are discussed. We confirm experimentally the mixed A* molecular/3s Rydberg character of the resonance at 292.1 eV. Atomic rearrangements after photoabsorption leading to the formation of novel cationic fragments and selective fragmentation to the CH2O2+ ion are also reported.
