Zeeman effect on the rotational levels of CCS and SO in the 3Σ– ground state.

SHINNAGA H. and YAMAMOTO S.

Abstract (from CDS):

Zeeman splittings of the rotational transitions of the CCS and SO radicals in the 3Σ– ground electronic state have been calculated. Since the coupling scheme of the rotational angular momentum and the electron-spin angular momentum is intermediate between Hund's cases (a) and (b), the mixing between the F1 and F3 levels has been treated strictly. In order to confirm the calculation, Zeeman splittings of the JN=43-32 and JN=32-21 lines of CCS are measured by laboratory microwave spectroscopy. The effective g-factors evaluated in the present study are of particular importance in the determination of the magnetic field strength of dense cores through polarization observations.
