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.
分子二价阳离子是火焰、等离子体化学和物理学以及行星高层大气化学中的重要双电荷阳离子。此外，它们还是能够在分子水平上储存相当多能量的奇特物种。这种几个电子伏特的高能量含量可以很容易地作为通过库仑爆炸产生的两个碎片单阳离子的平移能释放出来。出于这个原因，它们被提议作为一种新型替代推进剂。本主题综述论文报告了作者的研究小组在过去 40 年中通过实验和理论相结合的努力，在简单分子二价阳离子的生成和特性研究方面的主要贡献概述。
