V. Barone et al., COMPARISON OF CONVENTIONAL AND HYBRID DENSITY-FUNCTIONAL APPROACHES -CATIONIC HYDRIDES OF FIRST-ROW TRANSITION-METALS AS A CASE-STUDY, Chemical physics letters, 249(3-4), 1996, pp. 290-296
A parallel study by different conventional and hybrid density function
al methods has been performed for the whole series of binary cationic
hydrides of first row transition metals. The results show that hybrid
methods represent a significant improvement over standard density func
tionals, reaching an accuracy comparable to that of the most sophistic
ated post-Hartree-Fock approaches. Among the different hybrid methods,
the B3LYP variant seems to provide the most balanced results. In all
cases converged results are obtained with basis sets small enough to b
e applied in the study of large systems.
