New data on the electron-impact fragmentation of the amino acid proline molecule are presented as being related to the formation of the ionized products due to the influence of low-energy ionizing radiation on the above molecule. An extensive DFT-theory based on the theoretical approach enabled the main pathways of the proline molecules fragmentation to be elucidated. A series of the produced fragments have been identified. The absolute appearance energies for some of them have been both measured experimentally and calculated theoretically. The data of the experimental studies and theoretical calculations are compared and analyzed.
