Experimental and Theoretical Considerations

However, it cannot be decided at present which processes (degree of seawater-rock interaction or mixing ratio of seawater, igneous water and meteoric water) are important for the generation of Kuroko ore fluids solely from the isotopic studies. But experimental and theoretical considerations on seawater-volcanic rocks interaction and origin of hydrothermal solution at midoceanic ridges suggest that Kuroko ore fluids can be produced dominantly by seawater-volcanic rock interaction.

The rules for potential nucleobases have become better defined by synthetic biologists.27 It is appropriate to couple design to experimental and theoretical considerations related to heterocycles that might be generated under prebiotic conditions. NASA should place high priority on Earth-based experiments that define what heterocycles might have been formed, especially in cometary bodies and on early Earth. 

In A -unsubstituted triazoles (1 or 2 R R = H) prototropy between nuclear N centres may occur. When R and R are different, the equilibrium in Scheme 8 is not only of theoretical importance but may affect alkylation, acylation, prototropy between ring and substituents, ligand properties and so on. Most experimental and theoretical considerations favour IH (1) (or 2H (21)) as the predominant or only tautomer the 4H tautomer may play a comparable role. The paradox arises from the all too common oversimplification of the problem the tautomeric status of a given triazole need not be the same in solution, melt, solid or gas phase. Variation of substituents, solvents, temperature and the often ignored variation of energy input by different analytical methods provide a field of results rather than a unanimous decision for or against a certain tautomer.

The luminescence bands of [Ag(CN)2]/KCl are assigned, as shown in Table 2, to [Ag(CN)2ln exciplexes that differ in the value of n and in their geometry. The exciplex assignment of these bands is based on both experimental and theoretical considerations. The foiiowing is an overview of the evidence used for this assignment ... 

Gc. These studies are described in detail in Chapter 7, but essentially from experimental and theoretical considerations it was demonstrated that the adhesive fracture energy, Gc, for a crosslinked rubbery adhesive/rigid plastic interface could be divided into two major components ... 

Experimental results obtained by using P NMR of enzyme complexes of some specific enzyme systems are described in this section. These results are presented in two categories (1) inert enzyme-bound complexes of substrates, inhibitors, cofactors, and their analogs, and (2) equilibrium mixtures in the enzyme-bound form (i.e., where the substrates and products arc observed as they interconvert on the enzyme). The studies include a number of different enzymes however, the list is not complete. The enzyme systems chosen for description are expected to illustrate the experimental and theoretical considerations presented in Section II and indicate the kind of information that might be extracted by P-NMR studies of enzyme complexes and the limitations and difficulties of the method.
