In the article written by Yang Weitao (DOI: 10.1126/science.1158722), there are several spectacular errors that can be characterized and understood through binding curves, the perspective of fractional charges and fractional spins. As shown in the paper, the binding curves of H2+ computed by B3LYP and LDA are compared with the curve by HF. For verifying other DFT methods, some of them have been applied.
