Zeeman effect splitting coefficients for ClO, OH and NO in some Earth atmosphere applications

Journal article, 2020

We present detailed tabulated Zeeman effect splitting coefficients for ground-state ClO, OH and NO for F ≤ 10. These species are, together with molecular oxygen, common Zeeman-affected molecules in Earth’s atmosphere. The Zeeman effect is shown to be important mostly for OH. In proposed satellite observations of mesospheric OH, a circular polarization signal of close to 3 K can be expected. ClO and NO both show more than 1% circular polarization signal.
