Ultrafast dissociation of CD2Cl2 and CH2Cl2

In this paper, the ultrafast dissociation following Cl 2p core–shell excitation into the 10a1* antibonding orbital in CH2Cl2 and CD2Cl2 molecules is studied. It is observed the presence of atomic Auger lines associated to the decay of dissociated Cl* atoms. The choice of CH2Cl2 and CD2Cl2 molecules to study the competition between the atomic and molecular Auger decays, allow us to probe nuclear dynamics and electron relaxation occurring on a comparable time scale, keeping other parameters identical.In this paper, the ultrafast dissociation following Cl 2p core–shell excitation into the 10a1* antibonding orbital in CH2Cl2 and CD2Cl2 molecules is studied.
