The infrared (IR) and Raman spectra of triphenylene with intensities were calculated using both density functional theory (DFT, B3LYP method) and Moller-Plesset perturbation method of second order (MP2) with ccpVDZ basis set. Spectra were compared with experimentally measured; the agreement between the observed and calculated spectra is good in case of IR spectroscopy, MP2 simulated spectra wer...

This paper presents MarkPledge3 (MP3), the most efficient specification of the MarkPledge (MP) technique. The MP technique allows the voter to verify that her vote is correctly encrypted with a soundness of 1−2−α, with 20 ≤ α ≤ 30, just by performing a match of a small string (4-5 characters). Due to its simplicity, verifying the election public data (vote encryptions and tally) in MP3 is 2.6 t...

In this study, types of the intermolecular interactions, interaction energies, void analysis diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)zinc(II) dihydrate (Complex 1), diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)nickel(II) 2), diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)cobalt(II) 3), whose crystal structures were characterized before, investigated with help CrystalExplorer prog...

We have performed periodic density functional and periodic local MP2 calculations for the adsorption of hydrogen fluoride and water on the four low index surfaces (001), (100), (101) and (110) of magnesium fluoride. While the adsorption of HF is described well using B3LYP, MP2 is required for a good description of the adsorption of H2O. Post-optimization dispersion corrections of B3LYP are foun...

We discuss the present status and reliability of theoretical predictions of noble-gas hydride molecules. It is shown that the single-reference MP2 calculations can produce a rather inaccurate energy diagram for the formation of noble-gas hydrides, and this may mislead the theoretical predictions. We suggest that the computational dissociation energy of the HY precursors should always be compare...

The chiral self-discrimination of twelve molecules showing axial chirality has been studied. They included peroxides, hydrazines, carboxylic acids, amides, and allenes. The homo and heterochiral dimers of the selected compounds, that present two hydrogen bonds, have been studied by means of density functional theory ~B3LYP/6-311G**! and ab initio ~MP2/6-311G** and MP2/6-31111G**! methods. The e...
