Attosecond electronic and nuclear quantum photodynamics of ozone

ORAL

Abstract

In the last few years we reported a series of numerical simulations proving that it is possible to create an electronic wave packet and subsequent electronic motion in a neutral molecule photoexcited by a UV pump pulse within a few femtoseconds. The ozone molecule has been served as sample system. By using extreme ultraviolet probe pulse the splitting of the excited B state nuclear wavepacket were followed into a path leading to molecular fragmentation and an oscillating path, revolving around the Franck-Condon point with 22-fs wave packet revival time. Recent experiment was strongly corroborated with our full quantum-mechanical ab initio simulations.
