Title: Optical Zeeman spectroscopy of calcium monohydride

Abstract

The Zeeman effect in the ground and low-lying excited electronic states of calcium monohydride CaH has been experimentally investigated using optical Zeeman spectroscopy of the (0,0) band of the B{sup 2}{sigma}{sup +}-X{sup 2}{sigma}{sup +} and the (0,0) band of the A{sup 2}{pi}-X{sup 2}{sigma}{sup +} systems. The observed Zeeman-induced shifts and splittings of numerous branch features recorded near the natural linewidth limit were successfully modeled using a traditional effective Hamiltonian approach to account for the interaction between the (v=0) A{sup 2}{pi} and (v=0) B{sup 2}{sigma}{sup +} states and explicit inclusion of the interaction matrix elements for the heterogeneous perturbations between the (v=1) A{sup 2}{pi} and (v=0) B{sup 2}{sigma}{sup +} states. The determined magnetic g factors for the X{sup 2}{sigma}{sup +}, B{sup 2}{sigma}{sup +}, and A{sup 2}{pi} states are compared with previously assumed values and those predicted by perturbation theory.
