Phys. 114, 3949 (2001) Interaction energies of van der Waals and hydrogen bonded systems calculated using density functional theory: Assessing the PW91 model The present study shows that DFT using the PW91 functional is potentially useful for the evaluation of nonbonded interactions. This is certainly true for hydrogen bonded systems where the error in the computed binding energy is well below 20% in the worst case. The basis set dependence of the DFT interaction energies using the PW91 functional is relatively small, being in the range of 20%. The basis set dependence of the interaction energies of the hydrogen bonded systems is less than 7% ~or less than 0.5 kcal/mol! in the worst case, if the cc-pVTZ and larger basis sets are used. However, in contrast to the wave function methods, an improvement of the basis set does not necessarily lead to an improvement of the result. |
