| 摘 要： | 从非谐振的势能函数中推导出键级与振动频率的关系，得出简单有机化合物分子的伸缩频率随键级增大而增大的结论．并用Ｈｉｃｋｅｌ分子轨道法计算出酰胺、酰氯乙酰基的键级，结合推导结果阐明羰基上不同取代基对键级的影响是使＞Ｃ＝Ｏ伸缩频率位移的因素之一

| Abstract: | The principle of vibration frequency of simple organic compound upsurging with the increase of its bond order is obtained with inference from potential energy function of dissonan vibration.HMO is used to calculate the bond order of acetamicle,acetyl chloride and acetyl.The result shows that the change of vibration frequency of carbonyl group are caused by the substitute of the bond order of carbonyl group. |

| Keywords: | dissonan vibration potential energy function bond order vibration frequency HMO carbonyl group |
