Note that Equation (2.30) already requires two more parameters than Equation (2.28) does. Also, to estimate j3 and /32, we need to select definite occupied and empty orbitals on both C and D. Finally, as C and D approach more closely, the orbitals of the original reactants will become so changed as a result of mixing that they will be useless for further calculations. 

The notation and nomenclature employed arc those recommended in the IUPAC Manual of Symbols and Terminology for Physico-chemical Quantities and Units, Appendix II, Part 1.13 (Selected Definitions, Terminology and Symbols for Rheological Properties). Pure and Applied Chemistry, 1979, 51, 1213-8. Alternatives to D and a are respectively y and T. 

Type I. For parallel reactions with separate reactants, the analysis is easily handled, since the two steps are independent of each other. Indeed, the inclusion of Type 1 as a nearly complex scheme is not really necessary for the homogeneous batch reactions at constant volume treated here, since the yield and selectivity definitions are redundant in this case with rate and conversion. The system is important in heterogeneous systems, however, so we introduce it for later reference. For first-order, irreversible reactions ...

A review of the selected definitions suggests that there are many important determinants of solvent quality for specific apphcation. Some solvent parameters are conflicting, some not well quantified, and each solvent application requires a unique set of solvent performance criteria. It can be thus anticipated, prior to any analysis, that the chemical structure can be used as the best means of solvent classification for any application. Such a classification is used in this book because of its broad application. Chemical names used are the common names beeause they are generally understood by all solvents users. 

Once a compound is selected for development, further studies are performed in animals and man to support the safety assessment and ensure that optimum dosing regimens are selected. Definitive in vivo PK and toxicokinetic studies are performed but also more detailed in vitro studies, particularly for the assessment of drug-drug interactions. ADME/PK support is continued throughout development (pre-clinical and phases I-IV) and a summary list of the main activities is shown in Table 4. 

Most of the above analysis was carried out for macromolecules. One could also carry out an almost identical analysis for particles using the particle flux expression (7.3.198), as long as the particle dimensions are less than 0.1 pm. The following selectivity definitions have been used in FFF techniques for macromolecules (molecular weight M) and particles (particle diameter dp) ...
