The Paschen-Back Effect in NH3andN2O Microwave Spectra

The Paschen-Back effect in the microwave spectra of N${\mathrm{H}}_3$ and ${\mathrm{N}}_2$O has been investigated in this experiment with a resonant cavity spectroscope. These molecules are known to possess relatively small values of nuclear electric quadrupole coupling and thus favor the realization of the Paschen-Back effect without prohibitively high magnetic fields.
