1 The present article revisites the ability of the density-functional based tight-binding (SCC-DFTB) approach to model liquids by focusing on liquid water and liquid benzene under ambient conditions. dftb serpin family B member 3 Homo sapiens
2 To do so, we benchmark a recent correction for the SCC-DFTB atomic charges which allows for a drastic improvement of the pair radial distribution functions of liquid water as compared to both experimental data and density functional theory results performed in the generalized-gradient approximation. dftb serpin family B member 3 Homo sapiens
3 This allows us to rationalize the impact of nuclear quantum effects on the SCC-DFTB description of liquid water. dftb serpin family B member 3 Homo sapiens
4 This study evidences the rather good ability of SCC-DFTB to describe liquid water and liquid benzene. dftb serpin family B member 3 Homo sapiens
