我们把每个分子从最低能量把原子拉开,所需要的能量,叫裂解键能。
There's a bond dissociation energy going from the lowest available level in each molecule to the dissociation limit where we pulled the atoms apart.
And what we see here is now when we're combining the p, we have our 2 p x and our 2 p y orbitals that are lower in energy, and then our pi anti-bonding orbitals that are higher in energy.
这里我们看到,当我们结合p轨道时,在低能处我们有,2px和2py轨道,π反键轨道在更高的能级处。
