Hypothesis
Can the diatomic molecular ion FeH+ be identified in astronomical environments using X-ray absorption spectroscopy?
Conclusion
The study presents the first laboratory spectrum of FeH+ that can be compared with astronomical observations, suggesting its potential presence in the interstellar medium.
Supporting Evidence
- This is the first laboratory spectrum of FeH+ suitable for comparison with astronomical data.
- The study indicates that FeH+ cannot be ruled out as a component of the interstellar medium.
- The iron 3d occupation in FeH+ was found to be 6.24, consistent with quantum chemical calculations.
Takeaway
Scientists took a special picture of a molecule called FeH+ to see if it exists in space, and they found it might be there!
Methodology
X-ray absorption spectroscopy was performed on FeH+ at the BESSY II facility, using an electrospray ionization source and a linear Paul trap.
Limitations
The study's findings are based on laboratory data that may not fully represent the complex conditions of the interstellar medium.
