Dear Jyotirmoy, In your mail you have mentioned that you have chosen C6 parameters for carbon-nitrogen interaction to be 60.710, which is the C6 parameter of carbon atom. I want to know why you did not choose C6 as : (C6 of carbon * C6 of nitrogen)sqrt2. If you read Grimme's 2006 paper you can fi

Dear SIESTA users, I want to do Van der waals dispersion correction using SIESTA. I have used a dispersion potential of Grimme type as suggested in Grimme's paper (J. Comput. Chem. Vol 27, 1787-1799 (2006)). My system is a carbon nanotube and nitrogen molecule is confined within it. I have prepared
