Mixture of Hydrofluoric and Hydrochloric Acid• Simulations:1 HF, 3 HCl, 28 waters,15 ps, NVT, 330 K3 HF, 4 HCl, 25 w, 12 ps + 25 ps NVT, 330 K6 HF, 8 HCl, 18 w, 50 ps, NVT, 350 K, 20 ps, NVE, 320 K6 HF, 8 HCl, 18 w, 40 ps annealing + 60 ps, NVT, 350 K14 HF, 0 HCl, 18 w, 2x50 ps, NVT 350 K(in all simulations dt = 0.121 fs (5 au), = 500 au)• PBE GGA and Vanderbilt pseudopotentials, cut-off 35 Ry• all hydrogens were replaced with deuteriums• we wanted to see how HF is behaving in acid environment• K.
