EXCITATION AND IONIZATION OF FREON MOLECULES .4. ABSOLUTE OSCILLATOR-STRENGTHS FOR THE PHOTOABSORPTION (6-200 EV) AND THE IONIC PHOTOFRAGMENTATION (11.5-49 EV) OF CFCL3

Absolute photoabsorption oscillator strengths (cross sections) for CFCl3 (freon 11) have been obtained utilizing dipole (e, e) spectroscopy over the equivalent photon energy range 6-200 eV. The ionic photofragmentation branching ratios and the photoionization efficiency have been obtained from time of flight mass spectra recorded using dipole (e, e + ion) coincidence spectroscopy at equivalent photon energies from the first ionization threshold up to 49 eV. Absolute partial photoionization oscillator strengths for dissociative photoionization of CFCl3 have been obtained from the photoabsorption and photoionization data.
