Abstract :
Some characteristic energies are observed in the first derivative of the photoionization spectrum of tetramethylsilane (TMS) cyclohexane and 2,2,dimethylbutane (DMB). They could correspond to "auto-ionizing" states situated above the ionization threshold. Some of these energies are assigned to Rydberg series converging to a vertical ionization potential in gas phase and persisting in liquid phase.
