Lead molecule fragment analogs

An analogous procedure can be applied to the dicyanoethylene. We can dissect the molecule into an NC—CN fragment and a HC=CH fragment. The appropriate interaction diagrams are shown in Fig. 37. A consideration of these diagrams leads to the following conclusions. 

Abstract. The spectral dependence of photoluminescence and optical conductivity for the solid C6o and Cd-Q)0 films (with the admixture of C70 fullerenes) are studied under irradiation by argon ions with different doses. The fragmentation of the C6o molecules and the formation of the radiation defects, which are accompanied by appearance and increase in the intensity of the new component of the excitons emission, by decrease in the high-frequency optical conductivity spectral dependence to an analogous characteristic for the amorphous carbon films are observed with an increase in the radiation dose. This testifies that with the destruction of the molecules structure by ions the growth of the number of electrons, which are in the sp2 -hybridized state takes place. Furthermore, with the appearance of radiation defects the formation of the traps of the free charge carriers, which lead to a total decrease in the optical conductivity occurs.
