The Zeeman tuning of the A 6Sigma+-X 6Sigma+ transition of chromium monohydride.
The magnetic tuning of the low-rotational levels of the A (6)Sigma(+) (v = 1 and 0) states of chromium monohydride, (52)CrH, have been experimentally investigated using optical spectroscopy of the (0, 0) and (1, 0) bands of the A (6)Sigma(+)-X (6)Sigma(+) transition. The tuning of the numerous low-rotational lines in the A (6)Sigma(+)-X (6)Sigma(+) (0, 0) band can be accurately modeled using a single set of g-factors (g(S) and g(l)) which are close to the expected values. In contrast, the g-factors for the A (6)Sigma(+) (v = 1) state required to model the magnetic tuning of low-rotational lines in the A (6)Sigma(+)-X (6)Sigma(+) (1, 0) band are strongly dependent upon rotational and fine structure component and the determined effective values for g(S) deviate significantly from 2.002. Interpretation of the quantum level variation of g(S) is presented. The magnetic hyperfine structure of the (0, 0) and (1, 0) bands of the A (6)Sigma(+)-X (6)Sigma(+) transition is analyzed to produce proton Fermi contact, b(F) and dipolar, c, magnetic hyperfine parameters of 19(1) MHz and 34(5) MHz for the A (6)Sigma(+) (v = 0) state and 21(2) MHz and 30(7) MHz for the A (6)Sigma(+) (v = 1) state.
