Infrared spectra of phenyl acridine-9-carboxylates and their 10-methylated cationic derivatives were recorded and discussed. Experimental data were compared with theoretically predicted transitions at the DFT level of theory (using the B3LYP functional and 6-31G** basis set) for optimized geometries of molecules. Substitution influences the values of the wavenumbers of characteristic stretching and
记录并讨论了a啶-9-羧酸苯酯及其10-甲基化阳离子衍生物的红外光谱。实验数据与DFT理论水平上的理论预测跃迁(使用B3LYP功能和6-31G **基集)进行了比较,以优化分子的几何形状。取代影响特征拉伸和弯曲模式的波数值,即对应于酯基和含有杂环氮原子的分子片段的波数。所选原子组的实验确定的跃迁与理论预测值密切相关。还讨论了化合物理论上衍生的某些理化特征与所选谱带的红外频率之间的相互依赖性。
