Antibonding orbitals energies

Figure 5.2 Relationship between the bond strength and antibonding orbital energy.

The most important change when co-ordination number n changes is the value of A(n), the difference between bonding and antibonding orbital energy values ... 

We observe that the larger the value of A, the larger is the bond energy. This is an important result since A, the difference in bonding and antibonding orbital energies, in principle can be measured spectroscopically and, hence, spectroscopic measurements can provide indirect information on bond energies. 

The triplet excited state of H2 is obtained by promoting an electron to a higher-energy molecular orbital. This higher-energy (antibonding) orbital is written and can be considered to arise from two Is orbitals as follows ... 

What is the energy separation E2 — E of the bonding and antibonding orbitals in ethylene, assuming that the overlap integral S is 0.27 ... 

It is well known that bonding and antibonding orbitals are formed when a pair of atomie orbitals from neighboring atoms interaet. The energy splitting between the bonding...
