Trihydrogen cation, H, is a key player in the formation of new molecules and the cooling of interstellar gas clouds.

A new study from Michigan State University has uncovered fresh insights into these pathways, particularly in compounds known as methyl halogens and pseudohalogens.

The findings could reshape the understanding of H formation and impact on astrochemistry.

The study’s findings were achieved through a combination of ultrafast laser spectroscopy and high-level quantum chemistry simulations.

Even a small increase in H abundance due to these mechanisms could have significant implications.

Star formation models, which rely on accurate chemical composition data, may need revision to account for newly discovered reactions.
