  1. 价键理论VS分子轨道理论VB& MO 蒋思思07300440027 尹辛波07300440032 赵琳 07300440034

  2. Comparison of VB & MO

  3. Comparison of VB & MO

  4. Location Of Bonding Application Bonding Condition Ion Term

  5. Ion Term

  6. VB：very basic MO：more overall

  7. + + 1s 2s 2p + Bonding Condition 氧分子为什么有顺磁性？

  8. 为什么染料分子中大多含有芳香环？

  9. Location Of Bonding 定域 离域 一对电子组成一个共价键，电子局限于这两个原子之间 苯的3个π键连成一体成为一个大∏键，分布在整个分子上

  10. 分子轨道与能级 … … … hv 共振吸收 基态 激发态 激发态 Application

  11. 轨道类型和能级间隔 共轭双键使能级间隔缩小 Application

  12. 价键理论和分子轨道理论是从不同的角度去探索分子结构的真理。在许多问题上两个理论得出的定性结论是一致的。但在另外一些问题上，两种理论各有其优缺点。所以在更完善的分子理论建立起来之前，这两种理论均不可偏废。价键理论和分子轨道理论是从不同的角度去探索分子结构的真理。在许多问题上两个理论得出的定性结论是一致的。但在另外一些问题上，两种理论各有其优缺点。所以在更完善的分子理论建立起来之前，这两种理论均不可偏废。 ——徐光宪
