Abstract:
A homologous series of dextran-magnetite complex (DM) was synthesized using alkali-treated dextrans with various molecular weights from 1800 to 27000. The structure of DM particles in water, particularly effect on molecular weight of dextran, was studied. The number of dextran chains binding to a core is possibly determined by the steric hindrance between dextran chains covering core. The conformation of dextran chains may change from a fully extended state to a random-coiled state with an increase in molecular weight.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
