• So it's an Anti-bonding orbital.

    一个反键轨道

    youdao

  • So, let's start our discussion of a bonding orbital.

    让我们开始来讨论键轨道。

    youdao

  • And this again is what we're going to call a bonding orbital.

    同样我们键轨道。

    youdao

  • So any time you see a star that means an anti-bonding orbital.

    任何时候看到有个意味着它是键轨道。

    youdao

  • And so this lower level is called a bonding orbital, and it is a bonding molecular orbital.

    所以能级较低轨道叫做轨道,就是成键分子轨道。

    youdao

  • So we would label our anti-bonding orbital higher in energy than our 1 s atomic orbitals.

    我们应该把反轨道高于1s原子轨道能量的地方。

    youdao

  • Now, from your book as well, this is the pz's of the two atomic orbitals forming the bonding orbital.

    现在也是你们书上两个pz轨道,组成成键轨道

    youdao

  • And what you find is when you have a bonding orbital, the energy decreases compared to the atomic orbitals.

    你们发现轨道的时候,相比原子轨道能量降低

    youdao

  • It turns out that the antibonding orbital is a little bit higher from the atomic orbital level than the bonding orbital is lower.

    证明了,反轨道原子轨道,成轨道比原子轨道第。

    youdao

  • Where EVM is the sum of eigenvalue of bonding orbital-connection matrix of the alkyl group and PEI is the polarizibility of alkyl.

    EVM为醇烷基连接矩阵特征之和PEI为烷基极化效应指数。

    youdao

  • And the other thing to point out is that the energy that an anti-bonding orbital is raised by, is the same amount as a bonding orbital is lowered by.

    另外一个指出的事情,反轨道引起能量升高,键轨道引起的能量降低是相同的。

    youdao

  • So again, this is an anti-bonding orbital, and what you see is that there is now less electron density between the two nuclei than there was when you had non-bonding.

    同样的,轨道你们看到反键轨道的时候,两个原子核中间电子密度小了。

    youdao

  • So you should remember that any time we combine 2 s orbitals, what we're going to find is if we constructively interfere those two orbitals, we're going to form a bonding orbital.

    你们记住任何时候我们组合两个2s轨道,我们发现,如果我们把它们相长叠加,我们得到一个成键轨道

    youdao

  • Also, it is cylindrically symmetric around the bonding axis, so this is how we know that it's a sigma orbital.

    此外关于圆柱对称就是为什么我们知道sigma轨道

    youdao

  • Because we have paired set in a 2 s orbital, so all we're left essentially is two electrons that are available for bonding.

    因为我们一对2s轨道里已经配对了,所以剩下两个电子可以用来成键。

    youdao

  • So that's the idea of a bonding molecular orbital.

    就是键分子轨道概念

    youdao

  • So if we name this orbital, this is an anti-bonding molecular orbital So we had bonding and now we're talking about anti-bonding.

    分子轨道我们有了现在我们讨论反键。

    youdao

  • In addition, we introduced the natural bond orbital (NBO) methods, which is increasingly important in bonding analysis and can be used for DFT methods.

    另外我们介绍自然轨道(NBO)方法这种方法在成分析中显示越来越重要的作用,能够结合用于DFT方法中。

    youdao

  • The spatial configurations and bonding effects of Oxides of Nitrogen were explained by using the Valence-shell Electron Repulsion Theory, Hybrid-orbital Theory and Molecular orbital Theory.

    杂化轨道理论分子轨道理论阐明氧化物类型,给出了分子空间构型结构数据的解释

    youdao

  • Molecular Orbital Theory and Pericyclic Reactions: Modern concepts of bonding and aromaticity.

    轨道理论周环反应关于化学键芳香性的现代概念

    youdao

  • Molecular Orbital Theory and Pericyclic Reactions: Modern concepts of bonding and aromaticity.
