THE SPECTROSCOPY OF CRYSTAL DEFECTS - A COMPENDIUM OF DEFECT NOMENCLATURE [PDF]

open access: yes, 2002
The authors bring together tables of current defect nomenclature and a summary of the rules actually practised (rather than idealised schemes) in choosing such labels for signals obtained with a range of spectroscopies.

Halogen Bonding in Nucleic Acid Complexes

open access: yes, 2017
Halogen bonding (X-bonding) has attracted notable attention among noncovalent interactions. This highly directional attraction between a halogen atom and an electron donor has been exploited in knowledge-based drug design. A great deal of information has

Experimental structure determination of the chemisorbed overlayers of chlorine and iodine on Au{111} [PDF]

open access: yes, 2010
We have performed an experimental structure determination of the ordered p(sqrt[3] x sqrt[3])R30 degrees structures of chlorine and iodine on Au{111} using low-energy electron diffraction (LEED).

Competition between chalcogen bond and halogen bond interactions in YOX4:NH3 (Y = S, Se; X = F, Cl, Br) complexes: An ab initio investigation [PDF]

open access: yes, 2016
Using ab initio calculations, the geometries, interaction energies and bonding properties of chalcogen bond and halogen bond interactions between YOX4 (Y = S, Se; X = F, Cl, Br) and NH3 molecules are studied. These binary complexes are formed through the

Halogen Bonding in Two‐Dimensional Crystal Engineering

open access: yesChemistryOpen, 2020
Halogen bonds, which provide an intermolecular interaction with moderate strength and high directionality, have emerged as a promising tool in the repertoire of non‐covalent interactions.

Selective Adsorption of a Supramolecular Structure on Flat and Stepped Gold Surfaces

open access: yes, 2017
Halogenated aromatic molecules assemble on surfaces forming both hydrogen and halogen bonds. Even though these systems have been intensively studied on flat metal surfaces, high-index vicinal surfaces remain challenging, as they may induce complex ...

A theoretical simulation of the resonant Raman spectroscopy of the H2O⋯Cl2 and H2O⋯Br2 halogen-bonded complexes [PDF]

open access: yes, 2016
The resonant Raman spectra of the H2O⋯Cl2 and H2O⋯Br2 halogen-bonded complexes have been studied in the framework of a 2-dimensional model previously used in the simulation of their UV-visible absorption spectra using time-dependent techniques.

Combining high-resolution scanning tunnelling microscopy and first-principles simulations to identify halogen bonding [PDF]

open access: yes, 2020
Scanning tunnelling microscopy (STM) is commonly used to identify on-surface molecular self-assembled structures. However, its limited ability to reveal only the overall shape of molecules and their relative positions is not always enough to fully solve ...

Competition between hydrogen and halogen bonding in halogenated 1-methyluracil: water systems [PDF]

open access: yes, 2016
The competition between hydrogen- and halogen-bonding interactions in complexes of 5-halogenated 1-methyluracil (XmU; X = F, Cl, Br, I or At) with one or two water molecules in the binding region between C5-X and C4=O4 is investigated with M06-2X/6-31+G ...

an ion mobility-mass spectrometry study [PDF]

open access: yes, 2018
Coordinative halogen bonds have recently gained interest for the assembly of supramolecular capsules. Ion mobility-mass spectrometry and theoretical calculations now reveal the well-defined gas-phase structures of dimeric and hexameric [N⋯I+⋯N] halogen ...
