Electron and photon impact studies of CF3I

Differential cross sections (DCS) for elastic scattering and electronic and vibrational excitation of CF3I by electron impact have been measured using electron energy loss spectroscopy (EELS). Differential oscillator strengths are derived from EELS measurements and compared with photo-absorption cross sections. Assignments have been suggested for each of the observed absorption bands incorporating both valence and Rydberg tranistions. Vibrational structure in each of these bands is observed for the first time.
