Orientation diagrams

It is well known that the mechanism found by experiment is often incomplete, this expression meaning that the equations for the partial reactions which have been derived from the kinetics do not add together to give the equation for the overall reaction. Let us consider then an open sequence of four steps with the orientated diagram... 

In 1935 in a paper (19a) on the theoretical aspects of the method of 1931 a number of definitions and notations used in the foregoing paragraphs of the present paper were introduced. A further development of the method, especially concerning its application to catalytic (enzymatic) reactions appeared in 1949 (7b). In this the partition matrix and orientated diagrams are introduced. It contains also a discussion of the time necessary for the establishment of the steady state. 

Figure 12.28 Orientation diagram of shear rate y versus lamellar layer thickness d, whieh is controlled by the surfactant concentration, for water and sodium dodecyl-sulfate in the mass ratio 1.55 to 1 mixed with a solution of dodecane and pentanol. At low shear rates (region 1) defect-ridden lamellae appear, predominantly oriented parallel to the shearing surfaces (orientation c ). At intermediate shear rates (region 2), onions form, while at high shear rates (region 3), lamellae in orientation c again form, but with few or no defects.

Figure 13.19 Orientation diagram for PS-PI diblock copolymer atT — 136°C, just below 76dt-The frequencies coc and cod were obtained from linear viscoelastic data they mark the transitions from relatively elastic behavior at high and low frequencies to more dissipative behavior at intermediate frequencies (from Wiesner 1997, reprinted with permission from Hiithig Wepf Verlag.)...

Fig. 20. Spin-orientation diagram in the Hox Tbi x Fe2 system. Filled circles, filled triangles and filled squares correspond to experimentally determined Mossbauer spectra characteristic of the (111 >, < 110 > and < 100 > axes of magnetization, respectively. Open triangles correspond to intermediate types of spectra. The broken lines are the experimentally, and the solid lines theoretically, determined boundaries of regions with different directions of magnetization.

Figure 5 is a simplified representation of the Pourbaix Diagram for iron. It delineates the regions where immunity, corrosion and passivity can be expected. Similar diagrams (as well as the more chemically-oriented diagrams) are available in the monograph by Pourbaix (1). 

Typical orientation diagram plots obtained by X-ray diffraction for hot drawn film melt spun fibres, and cold drawn films of iso tactic polypropylene are shown in Fig. 50. It is noted that the crystal orientation change is... 

HCl Monohydrate. Simulations for the static and MAS spectra are shown on top (red line) of the experimental lines (in blue). The yellow-shaded region represented on the tensor orientation diagrams highlights the N-H---C1 interactions. Experimental and calculated and values are also shown for each compound.
