Abstract:CeC$_{3}$H$_{4}$ and CeC$_{3}$H$_{6}$ are observed in the reaction of Ce with propene in molecular beams and characterized by mass-analyzed threshold ionization (MATI) spectroscopy and relativistic quantum calculations. The MATI spectrum of each species displays two band systems, each consisting of vibronic progressions from Ce-C stretching and ligand bending excitations in the ionic states. The adiabatic ionization energies of CeC$_{3}$H$_{4}$ and CeC$_{3}$H$_{6}$ are 41035 (5) and 41868 (5) \wn, respectively. The two band systems are separated by 125 \wn for CeC$_{3}$H$_{4}$ and 60 \wn for CeC$_{3}$H$_{6}$. By comparing the splittings from the spectra with the relativistic calculations at the level of multiconfiguration quasi-degenerate second-order perturbation theory, we assign the two band systems to transitions from two spin-orbit levels of the neutral molecules.
