Nominal character

As described in Sec. 17, the process parameter of the highest importance is the gas velocity in the fluidized bed, referred to as the fluidizing velocity or the superficial gas velocity. This velocity is of nominal character since the flow field will be disturbed and distorted by the presence of the sohd phase and the turbulent fluctuations created by the gas/solid interaction. 

Certain types of bond, whilst nominally being considered as single , have in fact, sufficient double bond character , to render rotation about their axis, restricted . The one you are most likely to encounter, is the amide bond. Partial double bond character exists between the carbonyl, and the nitrogen, and may be represented as in Structure 6.12 ... 

This time, the alkene nominal double bond has sufficient single bond character to permit a certain amount of rotation, as resonance forms can be drawn (e.g., Structure 6.18). 

The strongly bent nature of the NBOs of W(CH2)3 is depicted in Fig. 4.19, confirming the inadequacy of a simple a/7t-bonding picture for this species. Both contour plots are plotted in a plane perpendicular to the CH2 plane, showing the expected bending of the nominal a- and 7t-bond-forming hybrids centered both on M and on C in directions above and below the internuclear M—C axis. While the NBOs can still be crudely described with nominal a and 7t labels, incipient banana-bond character is clearly significant. 

Measurement of / Haii at 50 mK in the field range of 22-27 T on the sample with x = 0.053 revealed that the conduction is of p-type, consistent with the acceptor character of Mn. The determined hole concentration was p = 3.5 x 1020 cm-3, about 30% of the nominal concentration of Mn (fig. 17) (Omiya et al. 2000). A similar value of the hole concentration, which is almost independent of x, has been obtained from the Seebeck coefficient assuming a simple model of the valence band (Osinniy et al. 2001). 

The enhanced resolution of ENDOR over ESR allowed a more detailed analysis of the spectrum of AgTPP, It was found that the nominally d-like odd electron had <38% 4d character.560... 

Most of the reported photochemical reactions of lanthanide complexes involve some type of redox behavior.147 Photolysis (254—405 nm) of Eu2+ in acidic aqueous solution, for example, results in photooxidation of the metal and generation of H2 (equation 50).148 While the excited states responsible for this reaction nominally arise from 4/ -+ 5d transitions localized on the metal, strong mixing of the 5rf-orbital with ligand orbitals endows these states with appreciable CTTL character. Photoreduction of aquated Eu3+ can also be driven with UV ( 254 nm) light149 and forms the... 

The transient process that follows after introducing the impulse perturbation to the feed is shown in Fig. 5. At the stable conditions stabilization of throughputs can be monotonous (curve 1 in Fig. 5a) and oscillating (curve 1 in Fig. 5b). The loss of stability for identical classifiers is always of fast stabilizing oscillation character but the oscillations occurs around the throughput values, which are different in comparison to the nominal ones. The reason for the appearance of these auto-oscillations is namely the similarity of... 

Importantly, the excited electronic states are not of pure XT vs. CT character, and the observed admixtures of electronic state character strongly depend upon the interface geometry. While the XT states exhibit significantly larger oscillator strength and, hence, photoluminescence intensity, some of the nominal CT states can acquire non-negligible photoluminescence by intensity...
