Abstract

Time-resolved photoelectron spectroscopy using vacuum-UV probe pulses enables observing ultrafast dynamics during and after passing through conical intersections (CIs). The ring-puckering CI plays a prominent role following the ππ* photoexcitation of furan. More than 90% of the excited molecules safely return to the original ground state, while the remaining 10% transforms into isomers after passing through the puckering CI.

摘要

使用真空紫外探测脉冲的时间分辨光电子能谱能够观测分子通过锥形交叉点(CI)期间及之后的超快动力学过程。在呋喃的ππ*光激发之后,环皱曲锥形交叉点起着重要作用。超过90%的受激分子安全返回原始基态,而其余10%在通过皱曲锥形交叉点后转化为异构体。
