摘　　要：对六种新型杀菌剂3-苯基-2-(4-硒基吗啉基)-5-苯基乙烯基-4H-咪唑啉-4-酮及其衍生物的红外光谱进行测定,并对其谱峰进行准确归属,研究结构表明,苯环上不同的取代基对骨架的影响很小,由于分子内的共轭体系,使得碳氮的伸缩振动向低波数区迁移大约50 cm-1。The FT - IR spectra of six novel agrochemical 4H - imidazol - ine -4 - one derivatives were measured, and main bands were assigned accurately. Research result showed that the different substituents on benzene rings had small effect on molecular skeleton. Due to the conjugate effect in molecules of the compounds, the vibrational wave numbers of （ C = N） stretching vibration of 4H - imidazoline - 4 - one was shifted by about 50 cm-1 toward h}wer wave number.
