Which consequence results when approximating molecular orbitals via linear combination of atomic orbitals functions?

💡 Explanation

The variational principle energy is satisfied because the linear combination provides an upper bound to the true ground state energy. Therefore the approximate energy is greater than or equal to the true energy, rather than precisely matching it or having lower, invalid values.
