The characteristic features of ir and uv spectra of 43 4H-pyrido[1,2-a]pyrimidin-4-one derivatives with electron donor or acceptor groups in position 3, and positions 6, 7, 8, or 9, respectively, have been systematically studied. On the basis of the spectra some conclusions have been drawn for the molecular structure. The negative solvent effect of the lowest-energy π → π* transition is investigated
分别在3位和6、7、8或9位带有电子给体或受体的43 4 H-吡啶并[1,2- a ]嘧啶-4-酮衍生物的ir和uv光谱的特征,已经被系统地研究过了。根据光谱,得出了分子结构的一些结论。通过PPP方法研究了最低能量π→π*跃迁的负溶剂效应。
