Summary
Researchers studied the Germanium Monoxide (GeO) absorption spectrum using synchrotron radiation. They confirmed three ionization limits and measured a new fourth ionization limit for the GeO(+) ion.
Area of Science:
- Physical Chemistry
- Atomic and Molecular Physics
- Spectroscopy
Background:
- Germanium Monoxide (GeO) is a molecule with complex electronic structure.
- Understanding its ionization potentials is crucial for various chemical and physical applications.
Purpose of the Study:
- To record the absorption spectrum of GeO.
- To determine the ionization limits of the GeO(+) ion.
- To validate theoretical calculations for these limits.
Main Methods:
- Absorption spectroscopy was performed using synchrotron radiation at the SUPERACO facility.
- The spectrum was analyzed to identify ionization thresholds.
Main Results:
- The first three ionization limits of GeO(+) (X(2)Sigma(+), A(2)Pi, B(2)Sigma(+)) were confirmed at 11.2814, 11.42, and 15.048 eV.
- The fourth ionization limit (C(2)Sigma(+)) was measured for the first time at 31.47 eV.
- Experimental results showed good agreement with theoretical predictions.
Conclusions:
- The study successfully characterized key electronic states of the GeO(+) ion.
- The newly measured ionization limit provides valuable data for theoretical modeling and understanding GeO behavior.
