Kinetic Studies of CH2Cl2 Photoionization Using Synchrotron Radiation
The kinetic processes of the photoionization and dissociation ionization of CH2Cl2 have been investigated under supersonic beam conditions using synchrotron radiation. The ionization energy of CH2Cl2 is 11.32l±0.01eV. Based on the measured appearance potentials (AP) of the daughter ions, the formation enthalpies (FE) of the ionic species, the bond dissociation energies (BE) and the dissociation energies (DE) of the parent ion have been estimated. The most possible channels of the VUV photodissociative ionization have been analyzed.
