Which consequence occurs when approximation functions poorly represent diatomic molecular orbitals?

A)Spurious charge density accumulation arises
B)Vibrational modes become degenerate
C)Rotational energy levels are quantized
D)Electronic transitions exhibit redshifts

💡 Explanation

Inadequate basis functions can cause numerical artifacts in computed charge densities because the linear combination of atomic orbitals (LCAO) method relies on accurate functional representations; therefore, charge accumulates spuriously rather than reflecting correct molecular electron density and behavior.
