Ohno potential

We have studies finite polyenes with long chain lengths employing the PPP model with Ohno parametrization. Even for the long range Ohno potential, the SDMRG results are found to be nearly exact... 

There are other approaches for calculations of the TERIs. The uniformly charged sphere model is used in LNDO/S, the multipole modeP is used in MNDO/d, AMl/d, and PM3(tm) the bipolar expansion of the Klopman-Ohno potential is used in PM3d. 

The electron-electron interactions are usually treated using the semiempiri-cal Ohno or Mataga-Nishimoto potentials. These expressions are interpolations between a Coulomb potential, e /Aneorij, at large separations and U for the interaction between two electrons in the same orbital (rjj = 0). For bond-lengths in A and energies in eV the Ohno potential is... 

Fig. 2.9. The on-site pseudopotential, Vj, of a linear chain of 100 sites, using the Ohno potential, eqn (2.55). On average, this is balanced by the electron-electron repulsion in systems with particle-hole symmetry.

Table 6.4 Excitation energies (in eV) of the key low-lying states for the undimerized six-site chain (U = 100 eV, t = 2.5 eV, and V(i) is determined by the Ohno potential, eqn (2.55))...

The variables and parameters in eqns (7.2) - (7.5) are defined in Chapter 4. Vmn (defined in eqn (2.55)) is the Ohno potential for the undistorted structure. For generality, we also include an extrinsic dimerization, represented by the term...

Figure 3 shows polarization curves for the anodic oxidation of H2CO at various metal electrodes recorded by Ohno et al. [38] in a solution maintained at 25 °C and containing EDTA (a commonly used complexant in electroless Cu solutions) and maintained at a pH = 12.5. After exhibiting exceptional activity at potentials less than -0.8 Y (SCE)2, the activity of Cu decreases at ca. 0.3 Y (SCE) this region of activity is more than adequate for electroless deposition of Cu. Although they... 

Maximum residues (in mg/kg FW) and time post-administration were liver, 0.1, 2 h fat tissue, 0.09, 96 h kidney, 0.07, 4 h skin, 0.03, 8 h brain, 0.01, 4 h muscle, 0.008, 4 h and blood 0.003, 4 h. Half-time persistence was 6.5-13 h for the rapidly decreasing phase, and 4.8—8.9 days for the slowly decreasing phase (Ohno et al. 1986) Dose-dependent alterations of brain potentials without behavioral signs of chronic toxicity (USEPA 1980)...

Interaction Between Partial Reactions. The original mixed-p)otential theory assumes that the two partial reactions are independent of each other (1). In some cases this is a valid assumption, as was shown earlier in this chapter. However, it was shown later that the partial reactions are not always independent of each other. For example, Schoenberg (13) has shown that the methylene glycol anion (the formaldehyde in an alkaline solution), the reducing agent in electroless copper deposition, enters the first coordination sphere of the copper tartrate complex and thus influences the rate of the cathodic partial reaction. Ohno and Haruyama (37) showed the presence of interference in partial reactions for electroless deposition of Cu, Co, and Ni in terms of current-potential curves.
