        Prof. Refaat M. Mahfouz ，Assiut university, Egypt；學(xué)術(shù)摘要：Abstract Complexation of technetium-99 and rhenium in low oxidized forms with thiosalicylic acid (TSA) were investigated by uv.-vis. spectrophotometry and HPL-chromatography.By CNDO-MO calculations of the proper structure of TSA, the charge densities, ionization potential, electron affinity and its dipole moment were studied. The violet sol煤tions of the Tc and Re complexes exhibit characteristic bands in the visible at 420,590 nm and 410,570 nm respectively. Comparative HPLC studies using MeOH/H2O as a mobile phase indicate the Re-TSA complex to be less stable than the Tc-TSA complex.
