自秋转达对 Sigma(o)Bonding ■ Electron density lies between the nuclei. A bond may be formed by s-s,p-p,s-p or hybridized orbital overlaps. ■ The bonding MO is lower in energy than the original atomic orbitals. The antibonding MO is higher in energy than the atomic orbitals.Sigma(σ) Bonding ◼Electron density lies between the nuclei. ◼A bond may be formed by s-s, p-p, s-p, or hybridized orbital overlaps. ◼The bonding MO is lower in energy than the original atomic orbitals. ◼The antibonding MO is higher in energy than the atomic orbitals
