P rtl IMol r Properties. The properties of individual components in a mixture or solution play an important role in solution thermodynamics. These properties, which represent molar derivatives of such extensive quantities as Gibbs free energy and entropy, are called partial molar properties. For example, in a Hquid mixture of ethanol and water, the partial molar volume of ethanol and the partial molar volume of water have values that are, in general, quite different from the volumes of pure ethanol and pure water at the same temperature and pressure (21). If the mixture is an ideal solution, the partial molar volume of a component in solution is the same as the molar volume of the pure material at the same temperature and pressure.

Examination of cyclopropanation through RT6 and RT7 reveals that a less conventional explanation may be required to rationalize the high reactivity of zinc car-benoids (Fig. 3.29). The structure of RT6 represents a pseudo-dimer as shown in RTS that has been further activated by coordination of zinc chloride to the oxygen of the chloromethylzinc alkoxide. This mode of activation is reminiscent of that observed in RTl. Cyclopropanation proceeding from RT6 through TS3 has an activation energy of 27.8 kcal mol . This represents a negligible decrease in the barrier to methylene transfer when compared to reaction from RTS.

Second, the INSTl, but not an RTl, may conceivably inhibit the virus production from the pool of resting CD4 T cells that are in a state of pre-integration latency (Murray et al. 2007). Upon activation, the preformed pro-viral DNA that is already located in the nucleus integrates into the genome of these cells, allowing them to contribute to the viral load. 

Finally, the third case corresponds to pumping of solutes with 0-0 transitions, Voo>v. In this case, the fluorescence spectrum, immediately after excitation, must be close to the steady state one and should not vary with time. From the physical point of view, this case corresponds to the situation, where solvates with a local field Rtl (corresponding to the equilibrium configuration in the excited state) are excited.
