Abstract

We investigate the multichannel dissociative ionization of C₂H₅OH in intense laser fields by the photoelectron-photoion coincidence momentum imaging and identify separately the ionization and subsequent electronic excitation in C₂H₅OH. From the energy correlation between a photoelectron and a fragment ion, we reveal the amount of the internal energy gained by C₂H₅OH⁺ from the laser field varies depending on the respective ionization and electronic excitation pathways. It is found that C₂H₅OH⁺ prepared in the electronic ground state associated with the moment of the photoelectron emission gains larger internal energy at the end of the laser pulse than that prepared in the electronically excited state at the moment of the photoelectron emission.
