Abstract

The magnetic tuning of the low rotational levels in the (v = 0) X²Σ⁺, (v = 0) A²Π, and (v = 0) B²Σ⁺ electronic states of calcium monofluoride, CaF, have been experimentally investigated using high resolution optical Zeeman spectroscopy of a cold molecular beam. The observed Zeeman shifts and splittings are successfully modeled using a traditional effective Hamiltonian approach to account for the interaction between the (v = 0) A²Π and (v = 0) B²Σ⁺ states. The determined magnetic g-factors for the X²Σ⁺, B²Σ⁺ and A²Π states are compared to those predicted by perturbation theory.
