article deals with the synthesis, spectral characterization and antimicrobial activity of phenylazo dyes. All of the synthesized phenylazo dyes were characterized using ATR-FTIR, FT-Raman, (1)H NMR, (13)C NMR, elemental analysis and mass spectroscopic techniques. Solvent effects on the UV-Vis absorption spectra of these phenylazo dyes were studied. Acid and base effects on the visible absorption maxima
本文涉及苯基偶氮染料的合成,光谱表征和抗菌活性。使用ATR-FTIR,FT-Raman,(1)H NMR,(13)C NMR,元素分析和质谱技术对所有合成的苯基偶氮染料进行表征。研究了这些苯基偶氮染料对UV-Vis吸收光谱的溶剂影响。还报道了酸和碱对苯基偶氮染料可见吸收最大值的影响。使用标准6-31G(d)基集,使用密度泛函理论(DFT)对分子进行结构和光谱分析,并通过与实验值进行比较来评估优化的几何形状和计算的振动频率。据报道4-(取代的苯基偶氮)-3,5-二乙酰氨基-1H-吡唑类具有抗细菌活性,
