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 Σ+2 -X Σ+2 and the (0,0) band of the A Π2 -X Σ+2 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 Π2 and (v=0) B Σ+2 states and explicit inclusion of the interaction matrix elements for the heterogeneous perturbations between the (v=1) A Π2 and (v=0) B Σ+2 states. The determined magnetic g factors for the X Σ+2, B Σ+2, and A Π2 states are compared with previously assumed values and those predicted by perturbation theory.
