Recently we reported a series of numerical simulations proving that it ispossible in principle to create an electronic wave packet and subsequentelectronic motion in a neutral molecule photoexcited by a UV pump pulse withina few femtoseconds. We considered the ozone molecule: for this system theelectronic wave packet leads to a dissociation process. In the present work, weinvestigate more specifically the time-resolved photoelectron angulardistribution of the ozone molecule that provides a much more detaileddescription of the evolution of the electronic wave packet. We thus show thatthis experimental technique should be able to give access to observing in realtime the creation of an electronic wave packet in a neutral molecule and itsimpact on a chemical process.
