1. Orbital Correlation Diagram for Second-Row Diatomic Molecules One of the oxides of nitrogen is the diatomic molecule nitric oxide (NO). This molecule is a by-product of combustion in air and is an important signaling molecule in mammals. (a) Draw the molecular orbital correlation diagram for NO. Please note that the ordering of the orbitals is similar to that of the O2molecule. (b) Write down the electron configuration for the ground electronic state of NO.
