The excitation of the lowest electronic states and vibrational excitation of cytosine (C) have been studied using electron energy loss spectroscopy (EELS, 0-100 eV) with angular analysis. The singlet states have been found to be in good agreement with UV-VIS absorption results on sublimed films, slightly blueshifted by about 0.1 eV. The EEL spectra recorded(More)
In thymine (T) and 5-bromouracil (BrU) the excitation of the lowest electronic states and vibrational excitation using EEL spectroscopy (0–100 eV) with angular analysis is reported. In the two molecules the singlet electronic states have been found blue-shifted by about 0.3 eV compared to the UV–Vis absorption results. Evidence has been found of triplet(More)
Electron collisions with gas phase coronene have been studied in the energy range 0-80 eV to investigate electronic and pure vibrational excitations, as well as the anion formation near zero energy. Quantum chemical calculations using time dependent density functional theory (TDDFT) have been performed for an improved data analysis. Results have been(More)
