摘要

The ((2) Pi(g3/2,1/2))nf Rydberg states of CS2 are investigated hy means of (3 + 1) resonance enhanced multiphoton ionization (REMPI) time-of-flight (TOF) spectroscopy. The excitation spectrum of jet-cooled carbon disulfide has been obtained in the 74 000-81 000 cm(-1) energy region. From the CS2+ mass selected REMPI spectra, the nf Rydberg series have been clearly identified and they have been found converging to the two spin-orbit components of the CS2+ (X (2) Pi(g)) ground state corresponding to the n=4-11 members. Comparison of the CS2+, CS+, S+ mass selected REMPI spectra gave a better insight of the competition between dissociation and ionization processes. The use of linearly nad circularly polarized laser light, selection rules and quantum defect considerations have led to a preliminary analysis of the measured nf complexes.
