 Title: THE MICROWAVE AND MAGNETIC RESONANCE SPECTRA OF VIBRATIONALLY EXCITED OH RADICALS Creators: Austin, Jared A.; Churg, Antonie; Levy, Donald H. Issue Date: 1973 Publisher: Ohio State University Abstract: The microwave and magnetic resonance spectra of excited vibrational states of the OH radical have been observed in a cavity microwave spectrometer. The v = 0 - 4 vibrational levels have been observed in the reaction of hydrogen atoms with $F_{2}O$ and the v = 0 - 6 levels have been observed in the reaction of hydrogen atoms with ozone. The $^{2}\Pi_{1/2} (J = 3/2)$ and $^{2}\Pi_{3/2} (J = 3/2, 5/2,$ and $7/2)$. A-doubling transitions have been observed at either zero or high magnetic field. The variation of hyperfine, rotational, and A-doubling constants with vibrational level have been extracted from the observed spectrum. There is some evidence that the A-doubling is caused primarily by mixing of the $A^{2} \Sigma^{+}$ electronic state with the ground state.
