Electron-pair densities of group 14, 15, and 16 atoms in their low-lying multiplet states
TL;DR: In this article, the 3P, 1D, and 1S multiplet states of five groups 14 atoms with p2 configurations, the 4S, 2D and 2P multiplets of five group 15 atom with p3 configurations, and the 3 P, 1 D and 1 S multiplets with p4 configurations were studied for all 15 atoms.

Group theory with applications in chemical physics
TL;DR: The first half of the book focuses on elementary topics, such as molecular and crystal symmetry, whilst the latter half is more advanced in nature. as mentioned in this paper provides a selfcontained and rigorous account on the fundamentals and applications of the subject to chemical physics, assuming no prior knowledge of group theory.

Rydberg series of charge-transfer excitations : Cl and H in rare gas crystals
H. Kunz,John G. McCaffrey,Majed Chergui,R. Schriever,Ö. Ünal,V. Stepanenko,Nikolaus Schwentner +6 more
TL;DR: In this article, the Rydberg series observed in the excitation spectra of Cl and H atoms isolated in the rare gas (Rg) crystals Kr and Xe are associated with the charge transfer species Cl−Rg+ and H −Rg+.

Amplitude correlations in nuclear resonance spectroscopy
TL;DR: In this article, both magnitudes and relative signs of inelastic decay amplitudes have been measured for proton resonances in the compound nuclei 45 Su, 47 V, 49 V, 51 Mn, 55 Co, and 57 Co. Resonances with orbital angular momenta 1,2 and 3 and five different values of J π were studied.

Origin of Hund’s multiplicity rule in quasi-two-dimensional two-electron quantum dots
TL;DR: In this article, the origin of Hund's multiplicity rules has been studied for a system of two electrons confined by a quasi-two-dimensional harmonic-oscillator potential by relying on a full configuration interaction wave function and Cartesian anisotropic Gaussian basis sets.
