Abstract

Using femtosecond time-resolved mass spectrometry (fs-MS), photofragment imaging (fs-PFI), and photoelectron imaging (fs-PEI), we have studied the dynamics of electronically excited molecules, from smaller (5–6 atom) systems to larger, substituted aromatic and biologically relevant heteroaromatic molecules. Work focus on fs-PEI with the aim to track the temporal populations of relevant optically bright and dark states populated and depopulated by ultrafast non-radiative transitions via conical intersections. The followings are some examples of research works.
