Figure 2 a) Valence bond structure for C70. b) Definitions of the various types of defect, each enclosed in a closed loop. The muonated centres are labelled. Types fl3, c and 63 refer only to one muonated centre because the other is symmetrically equivalent. The closed loops enclose the atoms which are allowed to relax in each calculation. 

Model-dependent comparison of two time profiles is best achieved in terms of the semi-invariants discussed earlier in the section on Characterization of Semi-invariants ( Moments ). This treatment is in accordance with the Level B definition of IVIVC, as proposed in several official guidelines. It makes full use of the underlying model that the data are presented by a distribution function, but no specific function is required. Although derived function parameters (e.g., Weibull, polyexponential, etc.) may be used, the computation may also be performed numerically on the observations as such. 

Figure 4-21 The concept of boundary layer and boundary layer thickness 5. (a) Compositional boundary layer surrounding a falling and dissolving spherical crystal. The arrow represents the direction of crystal motion. The shaded circle represents the spherical particle. The region between the solid circle and the dashed oval represents the boundary layer. For clarity, the thickness of the boundary layer is exaggerated, (b) Definition of boundary layer thickness 5. The compositional profile shown is "averaged" over all directions. From the average profile, the "effective" boundary layer thickness is obtained by drawing a tangent at x = 0 (r=a) to the concentration curve. The 5 is the distance between the interface (x = 0) and the point where the tangent line intercepts the bulk concentration.

Similar plots can be drawn at other temperatures. The constant b definitely depends upon alcohol concentration. The data are less certain, but a seems to show little dependence upon alcohol concentration. 

Enantioselective (enzymatic) cyclization of 1 could lead to either enantiomer 2 a or 3 a, depending on which face of the internal double bond is attacked at C-6 by the cation derived from the allylic pyrophosphate unit. Re- or Si-face cyclization (see the detailed discussion in Section 4.3.4.1.2.1., p 442 of 1 b would, however, lead to the diastereomers 2b and 3b. respectively. A thorough analysis of the NMR spectrum of the cyclization product of 1 b definitely showed that 2b was formed thus proving the absolute configuration of (-)-fl-irans-berga-motene to be 2a185.
