Hybridization effect on chemical potential and hardness — a quantum chemical study

The hybridization effect on two important quantities, chemical hardness abd chemical potential, has been studied by HF-SCF theory using a 6-31G basis set. The maximum hardness principle has been tested for CC and CH symmetric stretching with positive and negative mean amplitudes of vibration. For the above study, three different types of hybrid orbital molecules, CH4, C2H6, C2H4, and C2H2, have been used.
