Abstract:

Abstract Accurate electron densities and X-ray form factors of Li, Be, F and their ions have been calculated. Electron correlation, crystal fields and ionic charge transfer change the form factors by up to a few percent, mainly in the range of sin θ/ λ < 1/3 Â -1 . Although electron correlation and crystal fields are small perturbations, their effects on the density and form factor are not additive. Densities or form factors of atomic and ionic systems are very similar; [Li0F0] and [Li+F-] procrystals differ by an effective charge transfer of not more than 0.4 e. Charge transfer and charge

Abstract:

Abstract Partial atomic charges serve as a simple model for the electrostatic distribution of a molecule that drives its interactions with its surroundings. Since partial atomic charges are frequently used in computational chemistry, chemoinformatics and bioinformatics, many computational approaches for calculating them have been introduced. The most applicable are fast and reasonably accurate empirical charge calculation approaches. Here, we introduce Atomic Charge Calculator II (ACC II), a web application that enables the calculation of partial atomic charges via all the main empirical appro

Abstract:

An analysis of atomic charges is presented for simple alkanes. Basically, Mulliken's scheme is followed, except for the partitioning of CH overlap populations. This achieves a relative ordering of atomic charges which is independent of the basis sets used in abinitio calculations. The absolute magnitude of atomic charges, however, is basis set dependent. Extensive geometry and scale factor optimizations yield the following results (in 10−3 e units) for the carbon net charge in ethane: 69.4 (STO-3G), 55.1 (STO-3G + CI), 42.8 (4-31G), and 37.8 (4-31G + CI).

Abstract:

Charge preservation is a necessary condition in population analysis. However, one such constraint is not enough to solve the arbitrariness involved in the population analysis such as Hirshfeld population. This arbitrariness results in too small Hirshfeld charges and poor reproducibility of molecular dipolar moments. In this article, the preservation of the molecular dipole moment is imposed upon the Hirshfeld population analysis as another constraint to improve the original Hirshfeld charges. In the scheme each atomic dipolar moment defined by the deformation density is expanded as contributio

Abstract:

Polarization of atoms plays a substantial role in molecular interactions. Class I and II force fields mostly calculate with fixed atomic charges which can cause inadequate descriptions for highly charged molecules, for example, ion channels or metalloproteins. Changes in charge distributions can be included into molecular mechanics calculations by various methods. Here, we present a very fast computational quantum mechanical method, the Bond Polarization Theory (BPT). Atomic charges are obtained via a charge calculation method that depend on the 3D structure of the system in a similar way as a

Abstract:

Recent SuperHeavy Element (SHE) discoveries involve only a few events. The assignment of their mass and charge relies on calculations of the excitation function for the reaction and the measurement of their alpha decay, with cross-bombardments as a consistency check. However, a systematic and undetected charged particle evaporation channel would change the assignment. So, while the elements with atomic numbers \(Z=113\), 115, 117, and 118 complete the seventh row of the periodic table of the chemical elements, there is no direct proof of their atomic number, \(Z\). X-rays are a fingerprint of

Abstract:

It is proposed to analyse the first-order reduced density matrix of a molecular wave function in terms of the first-order reduced density matrices of different states of the constituent atoms. With this an unambiguous partitioning of the molecular charge distribution in terms of the atomic charge distributions is obtained. Simple practical formulae are derived, such that in many ab initio molecular wave function calculations the analysis proposed can be carried out routinely. The results obtained should be useful for the interpretation of molecular wave functions in terms of their atomic const

In May 2011, the Federal Circuit, in the case of Therasense Inc. v. Becton Dickinson & Co. involving blood glucose test strip technology, changed the standards for proving inequitable conduct. Following this change, a withheld reference must invalidate the patent in order to be material and support a charge of inequitable conduct.

Abstract:

AbstractThere is hardly a generic connection between the partial atomic charges, a useful concept in chemistry, and the “fractionalization” of the electron accomplished under extreme experimental conditions in solid samples. Nonetheless, there is a relationship on a philosophical level. There is no information of who first introduced the concept of partial atomic charges in chemistry. In contrast, the physicists whose experiment turned the electron into excitations carrying a partial charge and whose theory provided the interpretation received the Nobel Prize for their discoveries.

We present total charge exchange cross sections for collisions of Li(1s22s2S) with H(1s) in presence of a linear polarized laser field of intensity 0.05 ≤ I ≤ 1 TW/cm2 and wavelength 5 103 ≤ λ ≤ 14 103 Å. Our calculation shows that the laser field can increase the cross section of this reaction by a factor of ten at impact energies E < 0.1 ke V/a.m.u. The mechanism of this process is discussed and it is shown that both atomic and molecular radiative transitions can take place depending on the laser wavelength employed.
