Production and Characterization of Molecular Dications: Experimental and Theoretical Efforts.

ABSTRACT

Molecular dications are doubly charged cations of importance in flames, plasma chemistry and physics and in the chemistry of the upper atmosphere of Planets. Furthermore, they are exotic species able to store a considerable amount of energy at a molecular level. This high energy content of several eV can be easily released as translational energy of the two fragment monocations generated by their Coulomb explosion. For such a reason, they were proposed as a new kind of alternative propellant. The present topic review paper reports on an overview of the main contributions made by the authors' research groups in the generation and characterization of simple molecular dications during the last 40 years of coupling experimental and theoretical efforts.
