Which outcome occurs when approximating molecular orbitals using Slater-type orbitals?

A)Accurate cusp representation near nuclei
B)Analytical evaluation of multi-center integrals
C)Higher numerical accuracy far from nuclei
D)Simplified calculation of exchange correlation

💡 Explanation

Slater-type orbitals accurately represent the wavefunction cusp near the nucleus because they contain an exponential term centered around the nucleus location. Therefore, using STOs ensures proper electron-nuclear interactions, rather than analytical simplicity afforded by other functions.
