Assignment of the C K-Shell Photoabsorption Spectrum of CF3CN Molecule

Assignment of the total C photoabsorption spectrum of CF3CN in the K-shell region has been established with the help of an angle-resolved photofragment ion spectroscopy. The anisotropy parameters for the energetic CF3+ and CN+ fragments were evaluated at the selected photon energies. The linear C–C≡N skeleton basically held in this region since the strongly negative anisotropy parameters were obtained at the πCN* ← CF(1s) transition.
