Key Points

The study aims to measure the absolute ionization cross sections for CClF3 and CHClF2 when exposed to electron impacts.
Conducted experiments with 20–1000 eV electron incidence
Analyzed ionization and fragmentation patterns
Measured release of chlorine and fluorine
Recorded absolute ionization cross sections for CClF3 and CHClF2
Identified significant fragmentation channels with Cl and F release
Highlighted the environmental impact of these chemicals

Implication

Researchers report ionization cross sections of two CFCs, revealing their fragmentation effects on the environment.

Abstract

We report absolute ionization cross sections for CClF 3 and CHClF 2 upon incidence of 20–1000 eV electrons. The highest fragmentation channels indicate significant Cl and F release, illustrating the impact of these CFCs/HCFCs on Earth's atmosphere.
