interactionsself-assemblycatenanescyclophanesThe recent surge of interest in the control of molecular organization in both the solution state (i.e. self-assembly) and the solid state (i.e. crystal engineering) has led researchers to recognize increasingly the importance of weak non-covalent ...
Through-space interactionsA series of N -aryl-3,4-(9′,10′-dihydroanthracene-9′,10′-diyl)succinimides have been synthesized as model compounds to study the interaction of an aromatic π system with aliphatic H atoms and heteroatoms such as oxygen, sulfur, and fluorine. The steric ...
Heterogeneous perturbations2E+ ~ 2Π of largely different magnitudes are observed with high resolution in the vacuum-ultraviolet absorption and in the infrared emission spectrum of the NO molecule. The rotational interactions between2Σ+Rydberg states and levels of theB2Π non-Rydberg state are ...
With the help of the theory of long-range interactions, an improved value for the ground state dissociation energy is obtained,viz.D0″ = 22 184 ± 3 cm−1 (≡ 63.427 ± 0.008 kcal/mole ≡ 2.7504 ± 0.0004 eV).J. A. Coxon...
Interchain weak π-π interactions lead to two dimensional networks for [VO 2 (pabh)] and [VO 2 (path)]. On the other hand, [VO 2 (padh)] forms a two-dimensional network through interchain N-methyl-H…oxo interactions. Mononukleare Pervanadyl(VO 2 + )-Komplexe mit dreizä...

The3Π and3Σ states fine structure has been interpreted by a simple model, which includes spin–spin, and second-order spin–orbit interactions and also centrifugal distortion effects both on rotational and spin–orbit coupling parameters. The ν dependence of the different molecular parameters has...
Pi interactionsDoes the “chlorine” bond exist? Comparison of the properties of several π-electron-donor–acceptor complexes B⋅⋅⋅ClF and B⋅⋅⋅HCl (right and far right) reveals a parallelism that suggests that a “chlorine” bond, the analogue of a hydrogen bond, exists i...
This study investigates the influences and environmental preferences of amide–π interactions, a relatively unexplored class of charge-free interactions, in oligomeric phycocyanins. In a data set of 20 proteins, we observed 2086 amide–π interactions, all of which were part of the protein backbone...
The type I phosphatidylinositol 4-phosphate 5-kinase (PIP5K) family produces the critical lipid regulator phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) in the plasma membrane (PM). Here, we investigated the potential role of PIP5Kγ, a PIP5K isoform,
