Electronic static

The conrbinalion of C-R acts as snubber circuil lo prelect electronic (static) components from high dr/df. 

The parameters of the model were used for the calculation of the diamagnetic susceptibility Xd and the electron static (low frequency) polarizability a(0) (Ivanov-Smolensky G.A. et al, Acta Cryst. 1983, A39, 411). For ionic bonding and spherical symmetry of atoms the classical Langeuven equation is valid. So with account to the S5mimetry we will obtain ... 

Correlation effects in molecules are normally partitioned into near-degeneracy effects (static correlation) and dynamic correlation. Qualitatively they differ in the way they separate the electrons. Static correlation leads to a large separation in space of the two electrons in a pair, for example on two different atoms in a dissociation process. Dynamic correlation on the other hand deals... 

The electronic term which is the first term in the Hamiltonian written in Eq. (3.13) and used to derive the Solomon and Bloembergen equations (Eqs. (3.16), (3.17), (3.19), (3.20), (3.26), (3.27)) may be inappropriate in many cases, since the electron energy levels may be strongly affected by the presence of ZFS or hyperfine coupling with the metal nucleus. Therefore, the electron static Hamiltonian to be solved to find the cos values, i.e. all electron energy transitions, and their probabilities, will be, in general,... 

The intensity of the ESR signal is directly proportional to the electronic static susceptibility. The ESR intensity (Fig. 18) at high temperatures in the paramagnetic phase follows approximately the Curie-Weiss law. Interestingly, it has... 

The experimental measures of these molecular electric properties involve oscillating fields. Thus, the frequency-dependence effects should be considered when comparing the experimental results . Currently, there are fewer calculations of the frequency-dependent polarizabilities and hyperpolarizabilities than those of the static properties. Recent advances have enabled one to study the frequency dispersion effects of polyatomic molecules by ab initio methods In particular, the frequency-dependent polarizability a and hyperpolarizability y of short polyenes have been computed by using the time-dependent coupled perturbed Hartree-Fock method. The results obtained show that the dispersion of a increases with the increase in the optical frequency. At a given frequency, a and its relative dispersion increase with the chain length. Also, like a, the hyperpolarizability y values increase with the chain length. While the electronic static polarizability is smaller than the dynamic one, the vibrational contribution is smaller at optical frequencies. ... 

Low voltage contactors are usually fitted with purpose-made protection devices for gnarding against overloading and single-phase operation. These devices are used individually or in combination and operate on magnetic, thermal or electronic principles. Electronic static devices offer the widest range of time-current characteristics. 

Cobalt(ni).—The optical activity associated with d-d transitions in dissymmetric cobalt(iii) complexes has been examined in terms of a model which incorporates both ligand field theory and the one-electron static-coupling theory of optical activity. Expressions have been obtained which relate the sign of the net or total d-d rotatory strength to specific stereochemical features in the ligand environment. Sector rules based on these expressions have been proposed and tested. A model for predicting the photo-reactions and quantum yields of cobalt(iii) complexes has been devised. ...

The static NR contribution to axx" was with 11.78 au considerably smaller than the corresponding electronic value (501.3 au). For Pxxx, however, the NR contribution (-608.7 au) was much larger than the electronic one (-35.8 au). The vibrational contribution to the Pockels effect, computed in the infinite optical frequency approximation was found to be 42.9 au, approximately equal in magnitude to the electronic static value. In the same approximation, the vibrational contribution to the EFISH property, y(-2co co,a),0), was -40 au, thus much smaller than the electronic counterpart (40,201 au).

There is a second type of chiral quadruple-bonded species in which the twist is zero or close to zero. " In these cases the M02 unit must be treated as an achiral chromophore and the CD (which is weak) can be explained by one electron static coupling. This theory has also been used to explain the CD of singly bonded Rh2(5 -mandelate)4 (EtOH)2. ... 

Fault conditions, maintenance operations, and system reconfiguration require the load to be switched from one power source to another. This workis accomplished with an output transfer switch. As discussed previously, most UPS systems use electronic (static) switching. Electromechanical or motor-driven relays...
