摘要： Based on the independent-particle-approximation and the multiple-scattering self-consistent-field theory, we have systematically calculated the electronic struc-tures of sodium molecular Rydberg series, analysed the quantum defect μ and the electronic-vibrational interaction (i.e. dμ/dR). The influences of double excitation configuration on the Rydberg series have been discussed. The electronic structures of Rydberg states and related dynamic behavior in a sodium molecule have been eluci-dated. Our theoretical results are in fair agreement with the available experimental measurements.

Abstract: Based on the independent-particle-approximation and the multiple-scattering self-consistent-field theory, we have systematically calculated the electronic struc-tures of sodium molecular Rydberg series, analysed the quantum defect $\mu$ and the electronic-vibrational interaction (i.e. d$\mu$ /dR). The influences of double excitation configuration on the Rydberg series have been discussed. The electronic structures of Rydberg states and related dynamic behavior in a sodium molecule have been eluci-dated. Our theoretical results are in fair agreement with the available experimental measurements.
