Mass spectrometric methods are used to examine the H/D equilibrium isotope effects (EIEs) of cationic M(C2X4)+ complexes (X = H, D) of the coinage metals M = Cu, Ag, and Au. Different experimental ...

Two competing different reaction paths are the key for a rationalization of the counterintuitive experimental observation of a higher reactivity in the fluorine transfer reaction Ln++F–R → LnF++R (LnCe or Ho) of fluorobenzene compared to fluorome

Ab initio molecular orbital calculations at various, correlated levels of theory have been performed on eight isomers of the [H,O4,S2]- anion and six forms of [H2,O4,S2]. For the former species, the hypothetical O3SSOH- (9) ion is identified as the l

Combined mass spectrometric experiments and density functional theory (DFT) calculations have been performed to determine the regioselectivity and uncover the origin of the CH bond activation of benzocycloalkenes by “bare” FeI cations. The hydroc

It was found that the results of B3LYP calculations are not consistent throughout different implementations of this HF/DFT hybrid functional. The origin of this discrepancy lies in the two different formulations of the VWN local correlation functiona

Ab initio MO calculations at the MP2/6-311G** level of theory show that the thiosulfoxide H2SS is 143 kJ mol-1 less stable than the disulfane HSSH, separated by an activation barrier of 210 kJ mol-1. Using much higher levels of theory, these results

The cationic (C2H4)M+ complexes (M = Cu, Ag, and Au) have been examined by different ab initio molecular orbital, density functional (DFT), and density functional/Hartree−Fock (DFT/HF) hybrid methods using relativistic effective core potentials and
