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 dreizäh...
White - 1999 - 1452-1459 - onlinelibrary.wiley.com Direct reaction of ytterbium or europium metal with 2,6-diphenylphenol yields novel lanthanoid aryloxides, including a unique diytterbium(II) cation with aryloxides solely as bridging ligands (figure)....
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...
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 ...

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...
cation–π interactionsC—H … O H-bonding interactionsIt is generally understood that helical proteins are stabilized by a combination of hydrophobic and packing interactions, together with H-bonds and electrostatic interactions. Here we show that polar side-chain interactions on the surface can play...
As a result, samples can be run in a mobile phase suitable for the polymer rather than selecting conditions to minimise column interactions which leads to the risk of aggregate formation in polyelectrolytes. While it is possible to calculate the MW of a polymer eluting from an FFF channel...
