Which outcome occurs when representing electronic wave functions as gaussian-type orbitals in computational electronic structure methods, assuming incomplete basis sets?

💡 Explanation

Using incomplete basis sets means the energy is an upper bound because the variational principle dictates that the calculated energy approaches the true energy from above; therefore, the energy provides an upper bound rather than an exact or lower one since the functions are not complete.
