Molecular Orbital (MO)Theory What's a MO Atomic Orbitals (AO) Wave functions ( Molecular Orbitals(MO) Different‘shapes': -MO:o (sigma)and (pi) -AO:s,p,d,f etc
Molecular Orbital (MO) Theory Atomic Orbitals ( ) Wave functions ( ) Molecular Orbitals ( ) A MO O ψ Different ‘shapes’: – MO: σ (sigma) and π (pi) – AO: s, p, d, f, etc
Molecular Orbital (MO)Theory Molecular Orbitals from Is Atomic Orbitals: Two A0s Two MOs An antibonding Node Molecular Orbital has higher energy s and lower stability Antibonding MO A bonding 61 Molecular Orbital Bonding MO has lower energy H Atomic orbitals H2 Molecular orbitals and greater stability No.ofMO=No.ofAO used to“make”them
