Three chalcones with a 2,3-dihydrobenzofuran linkage were analyzed by applying the density functional theory (DFT) and B3LYP approach with the 6-311G(d,p) basis set in this report. Spectroscopic and theoretical analyses were used to examine the structures of these three chalcones. The chalcone molecules' HOMO-LUMO energy was determined. Chemical reactivity parameters and molecular electrostatic surface potential (MESP) plots were obtained to gain useful insight into the distribution of charge density.

Ebook "A structural and vibrational study of the chromyl chlorosulfate, fluorosulfate, and nitrate compounds" presents important studies related to the structural and vibrational properties on the chromyl compounds based on Ab-initio calculations. The synthesis and the study of such properties are of chemical importance because the stereo-chemistries and reactivities of these compounds are strongly dependent on the coordination modes that adopt the different ligands linked to the chromyl group.

A hydrated complex of 1,10-phenanthroline with Cu2+ cation was intercalated in the interlayer space of montmorillonite. This intercalation occurs initially by through a cation exchange mechanism in which the charge of the complex cation compensates the excess of the negative charge of the interlayer, then, once the cation exchange capacity (CEC) value has been reached, by direct adsorption of the sulfate salt of this complex (i.e. the cation together with its sulfate counterion).

Formaldehyde (FA, CH2 O) is one of the toxic volatile organic compounds that cause harmful effects on the human body. In this work, the interaction of FA gas with metal phthalocyanine (MPc) molecules was studied by employing density functional theory calculations. A variety of [MPc]a (M = Sc, Ti, and V; a = –1, 0, and +1) complexes were studied, and the electronic properties, interaction energies, and charge transfer properties of all of the studied molecules were systematically discussed.
