Electric Interactions

This is one approach to the explanation of retention by polar interactions, but the subject, at this time, remains controversial. Doubtless, complexation can take place, and probably does so in cases like olefin retention on silver nitrate doped stationary phases in GC. However, if dispersive interactions (electrical interactions between randomly generated dipoles) can cause solute retention without the need to invoke the... [Pg.76]

The electrolyte solution is lower in free energy G than it would be if the species did not interact electrically because of the energy liberated by moving ions of opposite charge together while separating those of like charge. The chemical potentials fit of the species, for the same reason, are smaller than they would be in the absence of electrostatic forces. By the equation,... [Pg.115]

Its magnitude is governed by the amount of electronic and nuclear nuclear charge that lies along the z axis along the C—bond. The shape of the interaction (electric field gradient tensor) is described by the asymmetry parameter (ti), which... [Pg.381]

How are cardiac cells coupled How do cardiac cells interact electrically These are important questions to be addressed and they lead to the topic of cardiac networking. Sperelakis [1979] distinguished three forms of transfer of excitation (1) mechanical transmission (2) chemical transmission, and... [Pg.2]

Key words 7,7,8,8-tetracyanoquinodimethane (TCNQ), methyl-TCNQ, anion-radical salts, IR absorption spectra, electron-phonon interaction, electric conductivity. [Pg.320]

Because water molecules are polar, they interact electrically (you know, like charges repel and unlike charges attract) with other molecules. For example, when you put sodium chloride (table salt) in water, the attraction between different parts of the water molecule and the ions that make up sodium chloride are strong enough... [Pg.73]

If the dielectric consists of Nx molecules, having mutually non-interacting electric dipole moments p, (241) reduces to the well-known Langevin-Debye formula ... [Pg.170]

Equation (8-16) is obviously similar to the corresponding equation (8-3) for interacting electric dipoles. The magnitude of the magnetic interaction energy relative to thermal energy is Wffijnin/k]jT. ... [Pg.377]

When a particle becomes charged by triboelectrification, two types of interactions may contribute to the deposition and adhesion of the particle, namely electrical double layers and Coulombic interactions. Electrical double layers are considered to result from the formation of a shell of oppositely charged electrical layers at the interface upon contact. Coulombic interactions result from the forces of interaction which arise between charged particles and uncharged surfaces. [Pg.133]

Since second-order nonlinear optical materials are anisotropic, their optical properties are described by tensors as discussed previously in Sect. 2.1.2. For a nonlinear optical process, the -th order nonlinear polarization is due to n interacting electric held vectors and is described by an (n -I-1) rank tensor composed of 3"+ tensor elements. In nonlinear optics, several fields with different frequencies l can be present simultaneously so that the electric field and the polarization are represented by... [Pg.102]

It occurred to me that neutrons, in contrast to alpha particles, do not ionize [i.e., interact electrically with] the substance through which they pass. [Pg.28]

Haskopoulos and MarouUs [10] studied the interaction electric properties of H20 Rg (Rg = He, Ne, Ar, Kr, Xe). Correlation effects have been taken into account by employing M0Uer-Plesset (MP2, MP4) and coupled-cluster theories (CCSD, CCSD(T)) in connection with flexible, carefully designed basis sets. Bara-nowska et al. [11] computed the interaction-induced axial static dipole moments, polarizabilities and first hyperpolarizabilities of HCHO (HF)n (n= 1,2). They employed a series of methods (e.g. MP2, CCSD(T)) in connection with various basis sets. [Pg.130]

Beta Partide This is a negatively charged (-1) particle emitted from the nucleus of an atom and has the mass and charge equal to an electron. They will interact electrically with cells they encounter, but because they have only half the charge of an alpha particle, they are less ionizing and cause less damage. They will travel up to several meters in air and a few millimeters in tissue. They are both an internal and an external threat (can burn the skin) but are easily shielded by thin plastic, glass, aluminum, or wood. [Pg.98]
