What is it about?
The photostability of molecular ions is fundamentally characterized by their absolute photodestruction cross-sections. In this work, we introduce a breakthrough methodology that enables measurement of this parameter with unprecedented efficiency, achieving speeds nearly three orders of magnitude faster than previously possible.

Why is it important?
Determining the absolute photostability of molecular ions that constitute the building blocks of life, along with other key biomolecules, offers profound insights into the processes underlying the origin of life on Earth and its potential emergence elsewhere in the universe.
Perspectives
The methodology presented in this work holds the potential to transform how absolute photodestruction cross-sections are measured in the future. We anticipate that the new measurements enabled by this approach will inspire both experimental and theoretical researchers to transcend the limitations of current techniques and explore uncharted frontiers.
