Natural range separation of the Coulomb hole

The Journal of Chemical Physics, 2022
A natural range separation of the Coulomb hole into two components, one of them being predominant at long interelectronic separations (hcI) and the other at short distances (hcII), is exhaustively analyzed throughout various examples that put forward the most relevant features of this approach and how they can be used to develop efficient ways to ...

Countercurrent Separation of Natural Products

Journal of Natural Products, 2008
An assessment of the technology and method development in countercurrent chromatography (CCC) and centrifugal partition chromatography (CPC), collectively referred to as countercurrent separation (CS), is provided. More than six decades of CS theory and applications are critically reviewed and developed into a practical guide to CS for natural products

Enantioselective Separation on a Naturally Chiral Surface

Journal of the American Chemical Society, 2004
Kinked-stepped, high Miller index surfaces of metal crystals are chiral and, therefore, exhibit enantiospecific properties. Previous temperature-programmed desorption (TPD) spectra have shown that the desorption energies of R-3-methylcyclohexanone (R-3-MCHO) on the chiral Cu(643)(R) and Cu(643)(S) surfaces are enantiospecific (J. Am. Chem. Soc.
