Reorganization during

The cytoskeleton undergoes extensive reorganization during mitosis, and is responsible for the equipartition of a diploid set of chromosomes to each daughter cell (McIntosh and Koonce, 1989 Wadsworth, 1993). 

Let us summarize the results obtained. The theory is restricted to nonadiabatic electron-transfer reactions. If only classical modes are reorganized during the transition, the rate constant for the oxidation is ...

The effect of ligands on the character and degree of the inner-sphere reorganization during electroreduction of aqua-, aquahydroxy-, hydroxy-, and ethylene-diamine tetraacetic acid (EDTA) complexes of Zn(II) [95] and electrochemical process of Zn(II) complexed by different ligands - glycinate [96], ethanol amine [97], azinyl methyl ketoximes [98], aspartame [99], glutathione [100, 101] and several cephalosporin antibiotics [102] -were studied at mercury electrodes in aqueous solutions. 

Separation of Electronic and Nuclear Motions. The polarizabilities of the ground state and the excited state can follow an electronic transition, and the same is true of the induced dipole moments in the solvent since these involve the motions of electrons only. However, the solvent dipoles cannot reorganize during such a transition and the electric field which acts on the solute remains unchanged. It is therefore necessary to separate the solvent polarity functions into an orientation polarization and an induction polarization. The total polarization depends on the static dielectric constant Z), the induction polarization depends on the square of the refractive index n2, and the orientation polarization depends on the difference between the relevant functions of D and of n2 this separation between electronic and nuclear motions will appear in the equations of solvation energies and solvatochromic shifts.

The chemical nature of amber is complex. Amber consists of complex mixtures of sesquiterpenoids, diterpenoids, and triterpenoids that have undergone polymerization and molecular reorganization during fossilization. Phenolic units may also be present. Baltic coast deposits, which contain about 8% succinic acid, are often called succinite. Amber is amorphous, and its infrared spectrum closely resembles those of nonvolatile resins from extinct pine trees. It is believed not to be a high polymer, the resinous state being accounted for by the complexity of materials present. Amber also serves as a repository for a variety of extinct species of insects.
