Assessment of density functional approximations for the hemibonded structure of water dimer radical cation
Assessment of density functional approximations hemibonded structure water dimer radical cation Chemical Physics
2012/4/20
Due to the severe self-interaction errors associated with some density functional approximations, conventional density functionals often fail to dissociate the hemibonded structure of water dimer radi...
Abstract: We study the Hirsch-Plotkin radical of stability groups of (general) subspace series of infinite dimensional vector spaces. We show that in countable dimension and some other cases, the HP-r...
