Errores en la identificación de números reales cometidos por ingresantes universitarios
(Universidad Nacional del Nordeste. Facultad de Ciencias Exactas y Naturales y Agrimensura, 2018-05-09)
En este trabajo se realiza un análisis estadístico descriptivo de los errores cometidos por ingresantes a las carreras Ingeniería Eléctrica, Ingeniería en Agrimensura, Ingeniería en Electrónica, Licenciatura en Ciencias ...
Multicenter (FX)n/NH3 halogen bonds (X = Cl, Br and n = 1–5). QTAIM descriptors of the strength of the X…N interaction
(Molecular Diversity Preservation International, 2017)
In the present work an in depth deep electronic study of multicenter XBs (FX)n/NH3
(X = Cl, Br and n = 1–5) is conducted. The ways in which X X lateral contacts affect the electrostatic
or covalent nature of the X N ...
Intermolecular perturbation in the self‑assembly of melamine
(Springer, 2016)
A theoretical study has been conducted on a set
of supramolecular complexes based on 1,3,5-triazine-2,4,6-
triamine, or melamine (M), with cyanuric acid (CA), trithiocyanuric
acid (TCA), and two mono-substituted ...
Halogen bonding. The role of the polarizability of the electron-pair donor
(Royal Society of Chemistry, 2016)
The nature of F–Br X–R interactions (with X = F, Cl, Br, I and R = –H, –F) has been investigated
through theoretical calculation of molecular potential electrostatic (MEP), molecular polarizability, atoms
in molecules ...
A theoretical study of the strong interactions between carbón dioxide and OH+ and NH2+ products resulting from protonation of 1,2-dioxirane-3-one and 1,2-oxaziridine-3-one, respectively
(Springer, 2016)
In this work, we investigate the nature of the O–
O and O–N interactions in protonated 1,2-dioxirane-3-one
derivatives and protonated 1,2-oxaziridine-3-one derivatives,
respectively. The quantum theory of atoms in
molecules ...
Lewis acid-base behavior of hypervalent halogen fluorides in gas phase
(Springer, 2017)
Theoretical studies on Lewis acid-base behavior of
hypervalent halogen fluorides, F3X and F5X (X = Cl, Br, I)
have been instrumental in guiding this work. We have also
examined whether the hole-lump concept explains the ...
Double hole lump interaction between halogen atoms
(American Chemical Society, 2015-03-31)
In this paper a theoretical study has been
carried out to investigate the nature of the unusual halogen−
halogen contacts in the complexes R−X···X−R (with R = −H,
−Cl, −F and X = Cl, Br, I). AIM, NBO, and MEP analyses
have ...
Theoretical characterization of the chemical bonds of some three-membered ring compounds through QTAIM theory
(Springer, 2015)
In this paper, we investigate the nature of the
carbonyl and the intraring C–C, C–N, C–O, N–N, O–O and
N–O bonds of cyclopropanone and the following cyclopropanone
derivatives: aziridine-2-one (1); oxirane-2-one
(2); ...
Protonated heterocyclic derivatives of cyclopropane and cyclopropanone : classical species, alternate sites, and ring fragmentation
(Canadian Science Publishing, 2015)
A computational study has been performed for protonated oxygen- or nitrogen-containing heterocyclic derivatives of
cyclopropane and cyclopropanone. We have searched for the most stable conformations of the protonated ...
Naturaleza de las interacciones Mδ+⋯δ+C-Oδ- en carbonilos metálicos : un estudio basado en la topología de la densidad de carga electrónica y su función laplaciana
(Sociedade Brasileira de Química, 2016)
nature of
the metal–ligand interactions, in the [Ti(CO)6]2-, [V(CO)6]-, [Cr(CO)6], [Mn(CO)6]+, [Fe(CO)6]2+ and [Co(CO)6]3+ complexes has been
studied by means of topological analyses of the electron charge density, using ...
