Permanent electric dipoles in B 1Π and D 1Π states of NaRb: Experiment and theory

摘要: The paper presents experimentally obtained permanent electric dipole moment values (μ) in electronically excited B 1Π and D 1Π states of 23Na85Rb 23Na87Rb isotopomer molecules for a number vibrational rotational levels (v′,J′). method is based on measuring relative intensities “forbidden” fluorescence lines appearing due to dc Stark effect induced e/f parity mixing particular (v′,J′)-level, combined with radio frequency–optical double resonance measurement Λ-splitting energy Δe,f. measured state μ are close 6 D, representing minor changes the level v′ varying from 0 12 J′ region between 7 50, while about 3 D v′=4, 5 6.
