Polarizability of a hydrogenic state
Physical Review A, 1996Using Floquet spectroscopy, we have measured the scalar and tensor polarizabilities of a nominally hydrogenic state of a multielectron atom. We obtain ${\mathrm{\ensuremath{\alpha}}}_{0}$=426.1\ifmmode\pm\else\textpm\fi{}16 MHz/(V/cm${)}^{2}$ and ${\mathrm{\ensuremath{\alpha}}}_{2}$=-66.3\ifmmode\pm\else\textpm\fi{}22 MHz/(V/${\mathrm{cm}}^{2}$) for ...

Polarizability of alkali clusters
Physical Review B, 1985Molecular-beam deflection measurements of the static electric polarizability per atom, \ensuremath{\alpha}/N, are reported for sodium clusters up to N=40. The quantity \ensuremath{\alpha}/N decreases from the atomic polarizability to approximately 150% of the bulk value, at N=40.

On the role of polarizability in QSAR
Bioorganic & Medicinal Chemistry, 2005The polarizability of a molecule, an important physical property, is currently attracting our attention particularly in the area of QSAR for chemical-biological interactions. In this report, the polarizability effects on ligand-substrate interactions has been discussed in terms of NVE (number of valence electrons) using additive values for valence ...

Magnetic Polarizability of the Electron
Nature, 1949THE anomaly of the magnetic moment of the electron has been explained by Schwinger1 as due to the interaction of the electron with the zero-point fluctuations of the radiation field. A particularly simple derivation has recently been given by Luttinger2. Luttinger considers the state of an electron in a constant magnetic field H such that its energy is

Core Polarizabilities in Metals
Physica Scripta, 1982Linear response formalism within the density-functional scheme is applied in a calculation of core polarizabilities in simple metals. While the core polarizability changes relatively little (around 10%) from its free-ion value in the alkalis, Mg and Al, large increases are found for metals like Ga, Cd, In, and Sn with full d-shells.

X Polarizabilities and hyperpolarizabilities
2009This chapter presents and discusses recent achievements towards determining and interpreting polarizabilities and hyperpolarizabilities of atoms, molecules, clusters, supramolecular assemblies, polymers, and aggregates. It evidences both the strong activities in the field and their dual character.

Hydrodynamics of Polarizable Liquids
Annals of Physics, 1993The complete hydrodynamic theory of polarizable and magnetizable isotropic liquids is presented. Using only input of universal acceptance, the Lorentz transformation, the macroscopic Maxwell equations, and the thermodynamics, a set of hydrodynamic equations of motion is derived rigorously, without any ad-hoc assumptions or residual ambiguities ...

The Simulation of Solvent Polarizabilities and Dipolarities with Polarizable Continuum Model
The Journal of Physical Chemistry BThe ability of polarizable continuum models (PCM) to simulate nonspecific solvent effects (dipolarity and polarizability) was evaluated by calculating the transition energies of 1,1,10,10-tetrabutyldecanonaene (ttbp9) and 2-N,N-dimethylamino-7-nitrofluorene (DMANF), basis of Catalán's polarizability (SP) and dipolarity (SdP) solvent scales ...

On the theory of polarizability I
Physica, 1939Abstract The polarizability of a set of electronic systems with perturbation potential V + FZ is discussed in the second and third order of approximation. A rigorous quantummechanical proof for the formula of Silberstein is given and an approximate expression is applied to He .

Relativistic Polarizable Embedding
Journal of Chemical Theory and Computation, 2017Most chemistry, including chemistry where relativistic effects are important, occurs in an environment, and in many cases, this environment has a significant effect on the chemistry. In nonrelativistic quantum chemistry, a lot of progress has been achieved with respect to including environments such as a solvent or protein in the calculations, and now ...
