VUV and low energy electron impact study of electronic state spectroscopy of CF3I

Abstract The electronic states of CF 3 I have been investigated using photon and electron energy loss spectroscopy from 4 to 20 eV (310 nm> λ >60 nm). Assignments have been suggested for each of the observed absorption bands incorporating both valence and Rydberg transitions. Vibrational structure in each of these bands is observed for the first time. Absolute photo-absorption cross-sections have also been measured and are compared with earlier measurements.
