The X-ray photoelectron spectra (XPS) of the core electrons of the carbon, oxygen, nitrogen, and fluorine atoms of antibiotics from the class of quinolones (nalidixic acid, norfloxacin, and enoxacin), having different antibacterial activities, were measured and interpreted. The integrated intensities of the π-π* and n-π* transition bands in the absorption spectra of the compounds were analyzed. Th...... hiện toàn bộ

In the reaction of terbium trifluoroacetate Tb(tfa)3(H2O)3 with diethylenetriamine (deta) in air, tetranuclear terbium hydroxotrifluoroacetate [Tb4(OH)4(tfa)3(deta)4(detadcH)2](tfa)4(detaH)(H2O) (Tb4) is obtained and characterized by single crystal X-ray diffraction (XRD), powder XRD, IR spectroscopy, and TGA. The structure of the complex cation with the isolated metal-oxygen cubane core {Tb4(μ-OH...... hiện toàn bộ
