用同步辐射光源测量了SF6和PF5在气相和固相中L2，3边的高分辨光吸收谱。在凝聚相的一些高能量跃迁的强度减少表明显着的里德堡字符与终止轨道。这一观察结果与多重散射Xα计算的结果一致，并表明里德伯轨道可以穿透电负性原子产生的势垒。
High-resolution photoabsorption spectra of SF 6 and PF 5 at the L 2, 3 edge in the gas and solid phase have been measured with synchrotron radiation. A reduction in the intensity for some of the higher-energy transitions in the condensed phase indicates significant Rydberg character associated with the terminating orbitals. This observation is consistent with the assignments suggested by multiple-scattering Xα calculations and suggests that Rydberg orbitals can penetrate into the potential barrier created by the electronegative atoms.
