| Abstract | ||
| The Charge Transfer complexes(CTC) between 7,7,8,8-tetracyanoquinodimethane (TCNQ) and some tellurium compounds have been investigated spectrophotometrically in the UV-Visible region. The values of energies of transition , ionization potential (IP),and the dissociation energies of charge transfer (CT). complexes excited state(w) of these complexes have been calculated and were in the range of 9.96 - 9.35 ev. The charge transfer parameters of the tellurium compounds as a donor with TCNQ as accepter which is represented by ECT. ,KCT. ,Δ G وΔ H, and Δ S ,have been estimated .The data was analyzed using Bensi- Hildebrand equation ,from which the formation of 1:1 charge transfer complex was concluded. | ||
