摘要: In this paper, by using resonance enhanced (2+1) multiphoton ionization (REMPI) of AsH3 and detecting the daughter molecular ions AsH+ and As+, a long progression discrete structure was obtained from 267 to 291 nm, which obeys the formula ν0(cm-1)=68875.3+504.1v′2+5.26v′22. Analysis of the spectrum has revealed that it belongs to 4d Rydberg state transition. Our assignment yields the 4d Rydberg state parameters Te′=67881.1 cm-1, ωe′=495.1 cm-1 and δ=0.962. Finally the 4d Rydberg state structure of AsH3 was discussed.
