Near-threshold resonances have been studied for Be-like ions with a focus on overlapping resonances among Rydberg series converging to different thresholds. The behavior of the overlapping as a function of Z and the approach to the limit of infinite Z are investigated. The 4s4p resonance is ...
Benzene, pyridine, pyridinium, andpyryliumcations form an isoelectronic series with decreasing electron densities at ring carbon atoms and have increasing susceptibility to nucleophilic attack. Pyrylium saltsare usually synthesized by condensation methods. ...

Combined with the previous Be isoelectronic series results, these calculations exemplify the level of precision that is now possible with Hy-CI in describing not only the ground state of Be and Be-like ions but also excited states (S and non-S, singlet and triplet) as well as Be-like ...

IntroductionThis paper reports synthetic, spectroscopic, X-ray crystallographic and computational studies on an isoelectronic series ofortho-carborane derivatives 1-X-2-R-1,2-C2B10H10(R = Ph, X = F, OH, O−, NH2or NH−,Fig. 1a). Throughout this paper ...
The behaviour of this repulsion is analysed in terms of the Fermi hole and the contraction of the wavefunction which one finds for the state of lowest energy. Numerical examples are given for the 1P and 3P states of the He isoelectronic series, the 1S, 1D and 3P states of the C and O...
This regularity is completely absent from the most accurate previous work on the He isoelectronic series, that of Frolov and Smith,15 and is a signal that the optimization performed by those authors was not complete. Sign in to download full-size image Figure 1.1. Nonlinear parameters α and ...
