# Molecular Orbital Sequence [duplicate]

Two highly respected books: Atkins, Chemical Principles 5th ed. and Clayden Organic Chemistry 2nd ed. don't agree on the orbital arrangement of the $2p$ orbitals of $\ce{N2}$. Clayden on page 94 states that it is $\sigma_{(2p)}, \pi_{(2p)}, \pi^*_{(2p)}, \sigma^*_{(2p)}$ and Atkins on page 118 states that it is $\pi_{(2p)}, \sigma_{(2p)}, \pi^*_{(2p)}, \sigma^*_{(2p)}$.
