| Abstract: | We report soft X-ray total ion yield and angular-resolved ion yield spectra of CF3I in the C 1s, I 3d and F 1s ionisation regions, and tentatively assign the observed electronic states. Anisotropy in ion yield is observed only for the C  transition, indicating that the dipole moment for this transition is parallel to the C3v. The effusive source of CF3I is heated to 800 K to produce a mixture of CF3 and I, and the resulting spectra are compared to those recorded at room temperature. |
