1·So it's an Anti-bonding orbital.

这是一个反键轨道。

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

让我们开始来讨论成键轨道。

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

同样，我们叫它成键轨道。

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

任何时候你看到有个星，这意味着它是反键轨道。

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

所以能级较低的轨道叫做成键轨道，这就是成键分子轨道。

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

我们应该把反键轨道标在，高于1s原子轨道能量的地方。

7·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，这是两个pz轨道,组成的成键轨道。

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

你们发现当你有个成键轨道的时候，相比原子轨道能量要降低。

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

这证明了，反键轨道，比原子轨道高，成键轨道比原子轨道第。

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

EVM为醇中烷基的键连接矩阵特征根之和，PEI为烷基的极化效应指数。
