Which mechanism limits spatial resolution when using electronic wave functions to model molecular interactions?

💡 Explanation

When modeling molecules using electronic wave functions, approximations to density functional theory (DFT) such as LDA or GGA, introduce errors in the calculated electron density distribution, degrading the ability to accurately represent electron interactions and thus spatial resolution. Therefore, DFT approximations limit resolution, rather than inherent quantum limitations, Born-Oppenheimer decoupling, or Pauli exclusion.
