Abstract
- Adequate polarization functions reduce the error of density functional theory (DFT) for the heat of reaction for CF4+ SiCl4from ∼9–12 kcal mol−1to ∼2–4 kcal mol−1, and using an improved density functional further reduces it to ∼1 kcal mol−1. This reaction was previously identified as a stumbling block for DFT, but we show that the problem with the previous calculations was not DFT but rather inadequate basis sets to account for intramolecular charge polarization.
