The “first molecule”: He-H+ as a theme to study chemical bonding by molecular modeling

Abstract

In April 2019, it was reported [3] the detection (for the first time, in the interstellar space; previous detections were in the lab) of a species that is considered the very first molecule formed in the universe: He^-H⁺(formed about only 100,000 years after the big bang). It was the beginning of chemical synthesis, and, of course, chemistry. In the present work it is reported as such chemical species can be employed as a very good theme to study chemical bonding by using molecular modeling.
