Abstract
Inelastic x-ray scattering spectra excited at the 1s(-1)π* resonance of gas phase O2 have been recorded with an overall energy resolution that allows for well-resolved vibrational progressions. The nuclear wave packet dynamics in the intermediate state is reflected in vibrational excitations of the electronic ground state, and by fine-tuning the excitation energy the dissociation dynamics in the predissociative B'(3)Πg final state is controlled.
摘要
已记录下气相 O2 的 1s(-1)π*共振激发的非弹性 X 射线散射光谱，其整体能量分辨率可实现良好分辨的振动进展。中间态的核波包动力学反映在电子基态的振动激发中，并且通过精细调节激发能量控制预解离 B'(3)Πg 终态中的离解动力学。
