Abstract:
Electronic excitation is shown to affect the structural properties of the Xe matrix at low temperatures. The lattice defect creation was studied using the selective vacuum ultraviolet (VUV) spectroscopy methods. The samples were excited by synchrotron radiation in the range of excitonic absorption. The temporal evolution of the intensity distribution in the band of molecular type self-trapped exciton luminescence was analyzed. A direct evidence for the creation and accumulation of point lattice defects in solid Xe via the excitonic mechanism was obtained for the first time. The model of permanent lattice defect creation and transformation is discussed.

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.
