Maximum coincidence

In other words, we estimate the spectrum of the AF-singlet ground state by applying a shift, to the calculated undectet spectmm. For this case we use an empirical shift of 13500 cm so as to yield maximum coincidence between the calculated and observed spectra, a value easily obtained, for example, if we had used the Slater-Condon integrals from the Fe ion in equation (1) rather than the values for neutral Fe. 

Euln2P2 shows a rather low resistance at room temperature of 10 Q cm. The temperature dependence, shown in Pig. 11.4, is suggestive of a semi-metal. The resistivity decreases as a function of decreasing temperature until about 100 K, at which temperature it increases dramatically to a maximum coincident... 

Enzymatic transesterifications in organic solvents follow Michaelis-Menten kinetics, and in quite a few cases, the values of v/Ku roughly correlate with the solvent s hydrophobicity (Zaks, 1988a). The dependence of the catalytic activity of the enzyme in organic media on the pH of the aqueous solution from which it was recovered is bell-shaped, with the maximum coinciding with the pH optimum of the enzymatic activity in water. 

After 67 h, cellulose in the form of Solka-floc was added as described above. There was an immediate increase in the CER at this point. The increase continued until t = 73 h, at which point there was a sharp decrease in CER. This did not coincide with complete depletion of glucose from the medium (Fig. 3). The enzyme activity increased continually up to a value of about 2.6 FPU/mL. This maximum coincided with the depletion of glucose and occurred at about t = 100 h. From the integrated area of the COz evolution (Fig. 1), one can estimate that the C02 evolved on cellulose was about 80% of the value obtained from glucose. 

Other workers348 d 124 have reported that commencement of the cobalt-catalyzed autoxidation of pure hydrocarbons, i.e., nonpolar solvent, is accompanied by oxidation of Co(II) to Co(III). The transformation is easily observed by the change in color from pale violet or pink [Co(II)] to intense green [Co(III)]. Similarly, manganese-catalyzed autoxidations were observed to start when Mn(II) was converted to Mn(III). The concentration of Co(III) reached a maximum during the course of autoxidation and then decreased. This maximum coincided with the appearance of aldehydes in the reaction mixtures. The authors also showed by calculation124 that reduction of Co(III) by a secondary product accounted for the observed kinetics much better than reduction by hydroperoxide. Hence, the decrease in concentration of Co(III) after it had reached a maximum was attributed to reduction by aldehydes (see Section II.B.3.e), which was much more facile than reduction by alkyl hydroperoxide [reaction (96)]. 

The resulting monoliths displayed dichroism, with a maximum coinciding with that of the maximum of the absorption band of the (unreacted) template molecule. The observed anisotropy of the monoliths (Ah. = h — h, ca. 0.02 AU) was comparable with that of common oriented polymer films. 

Before Slater s rules can be used, the two Slater determinants must be rearranged so that they have the maximum possible number of columns in common (recalling that each column swap causes a sign change). After the determinants are in maximum coincidence, we see how many spin orbitals they differ by and employ the following rules ... 

In Fig. 6 the variation of the emitted intensity near the Mjy ionization limit is plotted for a voltage difference equal to twice the threshold. The shape of the spectrum is the same whatever is the voltage. An emission is observed below the absorption peak its maximum coincides approximately with the position of the absorption curve inflexion point and its intensity varies with the accelerating voltage in the same way as does atomic line. This emission gives the occupied 5/ distribution convoluted with the Lorentz distribution of the 3 d j2 level. 

A consequence of the antisymmetry property of the determinantal wave functions is that the matrix elements can be evaluated according to the Slater rules. Before the application of the Slater rules the determinantal functions should be ordered in such a way that maximum coincidence among the positions of the spinorbitals is secured. Notice that each transposition in the position of spinorbitals alters the sign of the determinantal function. 

Redistribution of the space-charge of the excited carriers is presented in Fig. 1. Therewith at low temperatures, as seen in Fig. 2, the tunable photoluminescence band maximum coincides with the difference of the quasi-Fermi levels AF, which in turn is close to the effective energy gap Eg of the doped superlattice. At... 

During the reduction of xanthine oxidase the impulse polarographic wave displays two maxima at potentials 0.08 and -0.01 The position of the first maximum coincides with the enzyme redox potential. In a solution of denatured xanthine oxidase, the first maximum is absent. Accordingly, the view of the authors is that xanthine oxidase in this potential region is reduced in the native state. As for the other maximum, it is possibly associated with the reduction of sulfur-containing groups. 

The maximum coincided with a minimum of the distance between particle and copper surface calculated from capacitance measurements. Maximum and minimum also coincided with the potential of zero charge of the copper electrode. To explain maximum and minimum, a new force was postulated that depended on the reorientation of the solvation shell around particles and electrode surface. The orientation of the solvent molecules on the electrode surface should have a minimum at the pzc. On the particle side, formation of a close contact with the metal surface would be easier for hydrophobic particles with only a weak interaction with solvent molecules. A maximum co-deposition should be observed for hydrophobic particles at the pzc. A number of papers published experimental results that support this concept. Dedeloudis and Fransaer even measured the attraction of hydrophilic and hydrophobic particles to a metal surface by placing the particles on the tip... 

Figure 1 The different arrangements for SERRS the curves represent (A) molecular absorbance and (B) plasmon resonance. In (A) the molecular absorbance maximum and the plasmon absorbance maximum do not coincide position 1 represents excitation at the absorbance maximum, 2 that at the plasmon maximum. In (B) the molecular absorbance and the plasmon maximum coincide position 1 represents excitation away from the absorbance and plasmon maximum where the spectrum has a preresonant component, 2 that at the absorbance maximum and plasmon maximum.

The enhanced recovery of residual oil, which occurs as a consequence of wettability gradients in a reactive alkaline-acidic system, is illustrated in Figure 10. Incremental production in this tertiary flood begins about 0.6 PV after caustic injection and ends after injection of approximately 1.0 PV of caustic. This production is preceded by a pressure peak with a maximum which is two times the steady-state pressure drop of the secondary water-flood. The pressure drop maximum coincides with the concentration minimum of the hydroxyl ion species which elutes at the rear of the tertiary oil bank. 

The average H2/CO feed ratio, 0.19, is far away from the stoichiometric ratio of slightly above two. Consequently, the conversion of carbon monoxide is low, 5.1%. The hydrogen conversion is at a higher level, 53%. The response of the product fractions to the applied feed cycle is shown in Figure 2a. The Diesel fraction never exceeds 36 wt%, but this selectivity maximum coincides with a maximum in the hydrocarbon production rate as shown in Figure 2b.
