  NaRb 的 A 1Σ+–b 3Π 配合物的高分辨率光谱和通道耦合处理

  摘要：

  本文介绍了基于高分辨率亚多普勒光谱和强度测量、能量、跃迁矩和自旋轨道相互作用的从头算相对论计算的 NaRb 分子的完全混合 A 1Σ+–b 3Π 复合物的研究，以及作为反向通道耦合方法（ICCA）去扰动分析。采用双激光 V 型泵浦-探针激发方案来获得 A←X 跃迁频率到 16 个 A 态振动能级，从 v=6 到 v=21，J 从 8 到 23。此外，激光中的相对强度-已记录诱导的 A→X 荧光光谱，包括所有可观察到的转变为基态振动能级的进展，后者产生观察到的 A 态能级的明确 v 分配。

  The paper presents the study of the fully mixed A 1Σ+–b 3Π complex of the NaRb molecule based on high-resolution sub-Doppler spectroscopy and intensity measurements, ab initio relativistic calculations of energies, transition moments and spin–orbit interactions, as well as an inverted channel-coupling approach (ICCA) deperturbation analysis. A two-laser V-type pump–probe excitation scheme was employed

  Several series of laser-induced fluorescence lines of the heteronuclear alkali dimer NaRb have been observed when a mixture of sodium and rubidium is irradiated by the He–Ne, Ar+, or Kr+ laser line. The spectroscopic constants of the X 1Σ+ ground state have been determined and the potential energy curve has been calculated by the RKR method. RKR potential curves for the excited B 1Π and D 1Π have been determined by comparing the observed and calculated intensity distributions as well as the transition energies. The dependence of the transition dipole moment upon the internuclear distance has been estimated. The fluorescence of the D lines of Na and Rb atoms and a less intense fluorescence, which is assigned as a transition to the a 3Σ+ state in NaRb, have been observed. From the measured vibrational spacing, which can be followed close to the dissociation limit, the dissociation energy De of the a 3Σ+ state is determined to be 568±5 cm−1.

  The sub-Doppler high resolution excitation spectrum of NaRb was measured by selectively monitoring the fluorescence intensity from perturbed levels to the (1)3Σ+ lower state. Many transitions were observed to the (2)3Σ+ state perturbed by B 1Π. Energy shifts of the perturbed levels were analyzed and the spin–orbit coupling constant between the (2)3Σ+ and B 1Π states was determined, together with molecular constants of each state. Fully resolved hyperfine splittings, induced by the coupling of electron spin with both 23Na and 85Rb nuclear spins, were observed in the transitions. By analysis of the observed splittings, the mechanism of perturbation was confirmed as due to Fermi contact interaction and hyperfine constants of the 23Na85Rb (2)3Σ+ state were determined. The ratio of electron spin densities at 23Na and 85Rb in the (2)3Σ+ state is estimated to be 0.84:0.16.

  Polarisation labelling spectroscopy technique was employed to study the double minimum 6(1)Sigma(+) state of NaRb molecule. Six lines of an argon ion laser were used to label rovibronic levels in the electronic ground state and the excitation spectra in the 6(1)Sigma(+) <- X-1 Sigma(+) band system were recorded in the spectral range 24 100-26 500 cm(-1). Energies of 901 rovibronic levels of the inner well of the 6(1)Sigma(+) state were determined for two isotopomers of NaRb. The potential curve of the 6(1)Sigma(+) state was constructed using the inverted perturbation approach method. (c) 2005 Elsevier B.V. All rights reserved.
