Analysis of Rydberg Series of Ytterbium Monofluoride, YbF
Resonance-enhanced multiphoton ionization (REMPI) is used to characterize Rydberg states of 174YbF. Assignment of these Rydberg states to series that converge to various rotational and vibrational levels of the 174YbF+ cation leads to an accurate value for the ionization energy IE = 48706.57(8) cm–1 of YbF. The values for the rotational constants of the YbF+ X1Σ+ ground state are found as Bν = 0+ = 0.257(1) cm–1 and Bν = 1+ = 0.255(3) cm–1, while the vibrational transition energy is ΔG1/2 = 598.86(15) cm–1. Photoinduced Rydberg ionization (PIRI) measurements via a high-lying Rydberg state have been performed using an infrared free electron laser, confirming the ΔG1/2 value.
