定性分子轨道理论Qualitative Molecular orbital theory(5)定性huckel法和生成轨道法 其实今天本来是要讲超价化合物体系的,但是想起来一方面要在上一节基团轨道应用的基础上做延伸,不能跳的太快,而且今天的生成轨道法也是下一节讲述配合物时的必备方法。 这一节篇幅不会很多,重点是掌握这两个办法的基本思想。 首先我...
同时会形成一组能量更高的反键轨道。 3.2a1能量虽然比1e高,但是由于2a1之间重叠要强的多,使得2a1对应的成键轨道能量下降,比1e对应的反键轨道能量还低(本身反键轨道能量上升就大于成键轨道能量下降了),但由于重叠最大,2a1形成的反键轨道也是能量最高的。 得到上图分子轨道以后,我们就可以开始说结论了。 14个电子...
Molecular orbital theory is concerned with the combination of atomic orbitals to form new molecular orbitals New orbitals arise from the linear combination of atomic orbitals to form bonding and antibonding orbitals Bonding orbitals --- lower energy Antibonding orbitals--- High energy Dr Seemal Jelani...
Molecular Orbital Theory Molecular orbital theory describes covalent bonds in terms of molecular orbitals, which result from interaction of the atomic orbitals of the bonding atoms and are associated with the entire molecule. Atomic Orbital = belongs to only one atom Molecular Orbital = belongs to th...

Molecular orbital theory is a flexible model for describing electron behavior in main group and transition metal complexes. Chemical bonds and electronic behavior can be represented with several types of models. While simple models, such as Lewis dot structures and VSEPR theory, provide a good starti...

内容提示: 1Page 1Molecular orbital theory We would like a theory of bonding that can be visualized and is at least semiquantitative. We have a picture of atoms with an electronic structure described by orbitals. Why not do the same thing for molecules ? Employ the orbital approximationΨ(r1...
