    Structure determination of the tetracene dimer in helium nanodroplets using femtosecond strong-field ionization by Constant Schouder, Adam S. Chatterley, Florent Calvo, Lars Christiansen, Henrik Stapelfeldt

    Published 2019-07-01
    “…Dimers of tetracene molecules are formed inside helium nanodroplets and identified through covariance analysis of the emission directions of kinetic tetracene cations stemming from femtosecond laser-induced Coulomb explosion. Next, the dimers are aligned in either one or three dimensions under field-free conditions by a nonresonant, moderately intense laser pulse. …”
