The sphere optimization technique is related to the saddle method described in Section 2.2, and involves a. sequence of constrained optimizations on hyperspheres with increasingly larger radii, using the reactant (or product) geometry as a constant expansion point (Figure 9). The lowest-energy point on each successive hypersphere thus traces out a low-energy path on the PES.

The optimal conditions for the complexation were found. The luminescence of Tb " in (L ) complex was established to observed in a range of pH 2,0-11,0 with maximum at 7,0-7,5. The Tb (III) luminescence in complex with (L ) aslo depends on amount of reagents, solvent nature, amount of surfactants and trioctylphosphinoxide (TOPO). It was shown that introduction into the system Tb-L the 3-fold excess sodium dodecylsulfate (SDS) increases the luminescence intensity by 40 times and introduction into the system Tb-L the 3-fold excess TOPO increases the luminescence intensity by 25 times by the order value connecting with the crowding out of water molecules from the inner sphere of complexes. 

While not exhaustive, the following points for consideration will go far towards optimizing the control of safety and liability standards within the engineer s sphere of influence. 

True examples of single-site catalysts are enzymes, where active sites are made mainly by metalhc centers (mono- or polynuclear species) whose coordination sphere is completely defined by ligands [1-4]. The strength of enzymes is the combined effect of metal center activity with the specific behavior of metal coordination sphere hgands. These species play a key role, being optimized to create an environment suitable for (i) metal centers approaching and coordinating by reactants (ii) product removal from the catalytic centers at the end of the reaction in order to avoid further reactions.
