Özet

The performance of two local exchange functionals, OLYP and O3LYP, developed by Handy and Cohen (Mol. Phys. 2001, 99, 403), has been assessed for predicting activation barriers and reaction energies for a set of eleven pericyclic reactions for which experimental data are well established. The results are compared to B3LYP and CBS-QB3 results previously reported (Guner et al. J. Phys. Chem. A 2003, 107, 11445).
