Abstract: | The paramagnetic resonance absorption spectrum of the OD radical in the excited vibrational levels up to v = 5 of the ground , state has been observed at X-band frequencies. The theory of the Zeeman effect of a paramagnetic 2Π state of a light diatomic molecule has been applied to analyze the spectrum. The Λ-doubling frequencies, the molecular g factors, coefficients of the second order Zeeman effect, and the hyperfine interaction constants were determined for each of the vibrational levels. The experimental results agree reasonably well with the values calculated from (a) optical data and (b) ab initio data. The experimental determinations are still much better than theoretical calculations. |
