| Abstract: | The electronic states of the unsaturated organometallic carbene CrCH2+ are investigated using high-resolution translational energy loss spectroscopy. The observed energy loss feature (1.05 ±0.2 eV) is in good agreement with theoretical calculations which predict two higher lying states, 6B1, and 6A1 at 0.78 and 0.82 eV respectively, above the 4B1 ground state of CrCH2+. |
