摘要：

High-lying Rydberg states of jet-cooled vinyl chloride at 9.3-10 eV are investigated using 2 + 1 resonance-enhanced multiphoton ionization spectroscopy. Four Rydberg series are observed and tentatively assigned as due to the transitions of pi --> ns, np sigma, np pi, and nf Rydberg orbitals associated with quantum defects of 0.94, 0.89, 0.48, and 0.02, respectively. All of the four series converge to the same ionization energy limit corresponding to the ground state of vinyl chloride cation. The adiabatic ionization energy of vinyl chloride is determined to be 80720 +/- 6 cm(-1), in excellent agreement with previously reported values. (C) 2000 Elsevier Science B.V. All rights reserved.
