Natural Bond Orbitals Natural Bond Orbitals (NBOs) convert molecular orbitals to the form of localised bonding orbitals that correspond to Lewis structures. Natural bond orbitals attempt to provide the most accurate natural Lewis structure. The NBOs are localised and are thus different to MOs - it is important not to over-interpret NBOs - NBOs give an indication of bonding and electronic structure in the framework of Lewis structures. In this exercise you will explore the bonding description of methanol from...
