    Abstract

    Ionization and subsequent electronic excitation occurring within the same laser pulse (400 nm, 96 fs, 1.3 ∼ 18 TW cm-2) are separately investigated by measuring in coincidence an electron and a product ion produced from C2H5OH. It is revealed that the nascent population in the electronically excited C2H5OH+ prepared by the ionization decreases as the laser intensity increases, while the subsequent electronic excitation is enhanced through the resonant electronic transitions. Ionization and electronic excitation mechanisms are described based on the electronic-state distributions of C2H5OH+.
