Abstract:
The Frederickz transition and the dynamic scattering deformation in 4-alkyloxy-4'-cyanobiphenyl compounds are investigated by fluorescence spectroscopy and turbidimetry. The main characteristics of the Frederickz deformation, reversibility and threshold voltage, in the nematic and the smectic A phase are investigated by means of fluorescence spectroscopy. Furthermore, the dynamics of the Frederickz transition are studied as a function of temperature and applied voltage. The results obtained with both techniques are compared and correlate well.

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.
CFT focuses on...
