Distinctive onset of electron correlation in molecular tautomers

We investigate the attosecond response of the electronic cloud of a molecular system to an outer-valence ionization. The time needed for the remaining electrons to respond to a sudden perturbation in the electronic structure of the molecule is a measure of the degree of electron correlation. Using t...

Zusammenfassung:We investigate the attosecond response of the electronic cloud of a molecular system to an outer-valence ionization. The time needed for the remaining electrons to respond to a sudden perturbation in the electronic structure of the molecule is a measure of the degree of electron correlation. Using the ab initio multielectron wave-packet propagation method, we analyze the ultrafast many-body dynamics following the removal of different outer-valence electrons of two tautomers of the uracil molecule and show that this response time can be sensitive to the molecular structure and the symmetry of the ionized molecular orbital.
