Basis set convergence in extended systems: infinite hydrogen fluoride and hydrogen chloride chains
Christian Buth, Beate Paulus
Basis set convergence of the Hartree-Fock and the correlation energy is examined for the hydrogen bonded infinite bent chains (HF)_infinity and (HCl)_infinity. We employ series of…
