The Zeeman spectrum of the OH 2Π [formula omitted] state

Abstract

The J = 1 2 and J = 3 2 states of the X 2Π 1 2 level of OH have been studied in magnetic fields up to 0.8 T. The molecular beam electric resonance method was used. The Λ-doubling Zeeman transitions have been observed for the J = 1 2 singular level for the first time. The results were combined with data from the literature, which enabled a rather uncorrelated fit of all the g-factors with improved accuracies. The experimental value of the electronic spin g-factor is compared with the theoretical prediction.
