Covalent Bonding
... • The upper molecular state (with the anti-symmetric wavefunction) does not lead to bonding as it’s energy is higher than the energy of the free atoms. It is known as the anti-bonding state. • The lower molecular state (with the symmetric wavefunction) does lead to bonding as it’s energy is lower th ...

Degrees of freedom
... Now consider a diatomic molecule. In addition to three translational degrees of freedom it can also rotate about three axes X, Y and Z (Figure 1). The energy associated with axis X is very small however, and so we say that the molecule has five degrees of freedom. If we assume that the energy associ ...
