Frontier orbitals, that is, the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), are important indicators for the effect of adsorption on a metal. Due to charge transfer and hybridization, the HOMO–LUMO gap shrinks compared to the free molecule, and...
and will actually weaken the bond. Electrons in non-bonding orbitals tend to be associated with atomic orbitals that do not interact positively or negatively with one another, and electrons in these orbitals neither contribute to nor detract from bond strength.MO diagramFriedrich Hund...
定性分子轨道理论Qualitative Molecular Orbital Theory(2)双原子分子的分子轨道,轨道次级作用和多原子分子QMOT基本思路 好了,继昨天讲了一大堆的理论内容(包括还被 @杨知守前辈狠狠地制裁一遍 )以后,从今天起,接下来所有的内容将基本上跳出纯理论的框架,而开始进入定性分析的各个环节了。我们上一节已经… SOP男朋友...
Draw the electron dot diagram for H2CO and determine how many bonded pairs of electrons there are. What is the orbital diagram for the nitrogen in the molecule below following hybridization (any lone pair electrons are in hybrid orbitals)? What is the orbital diagram for nickel? What is the...
To a first approximation the ionization energy is equal to the energy of the orbital from which the electron originates in the ground-state molecule. This is known as Koopmans' theorem, and allows each signal in the spectrum to be assigned to an orbital. Koopmans' theorem provides evid...
I thought I understood the molecular orbital theory but this practice question is making me confused. 1. For a diatomic molecule of oxygen (O2), we define the bond as lying along the z axis. a) Draw the valence MO diagram for O2. Include labels for molecular orbitals. ...
Figure 4. MO energy diagram for O 2 . Eight electrons from each oxygen atom add up to 16 electrons in the O 2 molecule. They combine to form the molecular orbitals indicated above. The MO theory also works well for larger molecules such as N 2 O, CO 2 , and BF 3 and for ions ...
