Correlated States in Polyenes and Ion-Radical Organic Solids,-overlapping, open-shell systems. Site representations and valence bond (VB) methods are required for such correlated electronic states. The complete CI problem in models based on one valence state per site is treated by diagrammatic VB theory by expanding correlated states in terms of conventional预防注射 发表于 2025-3-28 19:29:30

,“New” Molecular Bound and Resonance States,ere that “new” bound and resonance states can occur in a variety of problems involving coupled wave equations. Several examples are discussed, the most important one involving the bound and resonance states of van der Waals complexes.Isolate 发表于 2025-3-29 06:12:28

Studies of Intermolecular Forces by Vibrational Spectroscopy,spectroscopy at low temperatures, their small frequency shift Δν needs small half width of bands. The sign of Δν of bending modes of XH groups is able to differ between van der Waals forces and H-bonds. The Badger-Bauer rule relation between Δν and H-bond energy is discussed as well as the relationIncompetent 发表于 2025-3-29 16:49:13
Intermolecular Forces and Spectra in Weak Charge Transfer Interactions,l reactivity, probably the most characteristic property of EDA complexes is the appearance of an intense absorption band that is not present in the separated donor and acceptor species. This band, often broad and structureless, usually is in the visible and/or near ultraviolet regions, giving rise iBenign 发表于 2025-3-29 21:29:20

Electrostatic and Topological Interactions in DNA, Poisson-Boltzmann equation. The importance of the ions correlation and of the short range interactions is evaluated. The influence of the interactions between the different DNA molecules on the activity coefficients of the co-ions and of the counter-ions is studied.
