Further, it describes in detail adjustment subset which complete is based. Two noteworthy additions are bound-state rms charge radii proton deuteron tests exactness Josephson quantum-Hall-effect relations ${K}_{\mathrm{J}}=2e∕h$ ${R}_{\mathrm{K}}=h∕{e}^{2}$, where ${K}_{\mathrm{J}}$...
The formation of intramolecular hydrogen bonds has a very pronounced effect on molecular structure and properties. We study both aspects in detail with the aim enabling more rational use this class interactions medicinal chemistry. On basis exhaustive searches crystal databases, we derive propensities for bond five- to eight-membered ring systems relevance drug discovery. A number motifs, several which are clearly underutilized discovery, analyzed by comparing small molecule protein-ligand...
The International System of Units (SI) is founded on seven base units, the metre, kilogram, second, ampere, kelvin, mole and candela corresponding to quantities length, mass, time, electric current, thermodynamic temperature, amount substance luminous intensity. At its 94th meeting in October 2005, Committee for Weights Measures (CIPM) adopted a recommendation preparative steps towards redefining kelvin so that these units are linked exactly known values fundamental constants. We propose...
Results are given of a calculation the self-energy radiative level shift order $\ensuremath{\alpha}$ $2{S}_{\frac{1}{2}}$ and $2{P}_{\frac{1}{2}}$ states in strong Coulomb potential. The is evaluated numerically to all orders $Z\ensuremath{\alpha}$ for $Z$ range 10-110. An estimate obtained effect terms high on Lamb hydrogen. With this taken into account, theoretical value $\mathcal{S}=1057.864(14)$ MHz.
Sufficient progress towards redefining the International System of Units (SI) in terms exact values fundamental constants has been achieved. Exact Planck constant h, elementary charge e, Boltzmann k, and Avogadro NA from CODATA 2017 Special Adjustment Fundamental Constants are presented here. These recommended to 26th General Conference on Weights Measures form foundation revised SI.

A calculation of the self-energy radiative correction to energy level an electron in $2{S}_{\frac{1}{2}}$, $2{P}_{\frac{1}{2}}$, or $2{P}_{\frac{3}{2}}$ state a Coulomb field, with nuclear charge $Z$ range 10-110, is described.
The kilogram, the base unit of mass in International System Units (SI), is defined as international prototype kilogram. Clearly, this definition has effect fixing value to be one kilogram exactly. In paper, we review benefits that would accrue if were redefined so fix either Planck constant h or Avogadro NA instead , without waiting for experiments determine currently underway reach their desired relative standard uncertainty about 10−8. A significant reduction uncertainties SI values many...
