The electron resonance spectra of BrO, IO and SeF inJ=5/2 rotational levels

Abstract
The electron resonance spectra of BrO, IO and SeF in the J = 5/2 rotational levels of their ground 2II states have been observed and analysed. Comparison of these results with those obtained in the J = 3/2 levels leads to values for corrections to the magnetic moment arising principally from third-order effects of the spin-orbit coupling.
