Abstract

We have demonstrated a rovibrational-state-selected photoionization experiment using an IR laser and high-resolution VUV-synchrotron radiation. The VUV photoionization of acetylene [C₂H₂(X^~ ¹∑⁺_g; v₃ = 1, J' = 8 or 10] prepared by IR excitation reveals three strong autoionizing Rydberg series converging to C₂H₂⁺(X^~ ²∏_u; v⁺₃ = 1) with little ion background interference. Rotational transitions resolved for the Rydberg states provide an estimate of ≈ 1.8 ps for their lifetimes. This experiment opens the way for state-selective photoionization studies of polyatomic molecules using VUV-synchrotron radiation.
