飞秒时间分辨的光电子影像对3-甲基吡啶分子超快动力学研究
Studies of Ultrafast Dynamics of 3-Picoline with Femtosecond Time-Resolved Photoelectron Imaging
摘要
Abstract
The ultrafast dynamics of excited states in 3-picoline was studied using femtosecond time-resolved photoelectron imaging, coupled with time-resolved mass spectroscopy. An ultrafast internal conversion from the S2 state to the vibrationally excited S1 state in about 910 fs was observed. This secondary-populated S1 state further deactivates to the S0 state in 2.77 ps. The photoelectron energy and angular distributions show ionizations from the singlet 3p Rydberg states. Two 400 nm photon excitations to the 3s Rydberg state suggest that this state probably decays to the ground state in 62 fs.关键词
