The &BS section seems to be really usefull but I am struggling to obtain the actual electronic configuration of my system (Y3Fe5O12). I am trying to model theese Fe3+ (d5) ions, where Fe1 will be spin up and Fe2 will be spin down using the attatched &BS section on the input. <o:p></o:p> <div> <o:p> </o:p> </div> <div> &KIND Fe1 ELEMENT Fe BASIS_SET SZV-MOLOPT-SR-GTH POTENTIAL GTH-PBE-q16 &BS &ALPHA NEL -2 -1 L 0 2 N 4 3 &END &BETA NEL -2 -4 L 0 2 N 4 3 &END &END &END KIND &KIND Fe2 ELEMENT Fe BASIS_SET SZV-MOLOPT-SR-GTH POTENTIAL GTH-PBE-q16 &BS &ALPHA NEL -2 -4 L 0 2 N 4 3 &END &BETA NEL -2 -1 L 0 2 N 4 3 &END &END &END KIND<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> The electronic configuration of Fe is [Ar] 4s2 3d6 and the one of Fe3+ ions is [Ar] 3d5, so I tried to extract both 4s electrons and 1 of 3d in each spin orientation, but in the output I see that there is something wrong:<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Guess for atomic kind: Fe1 Electronic structure Total number of core electrons 10.00 Total number of valence electrons 11.50 Total number of electrons 21.50 Multiplicity triplet Alpha Electrons S [ 1.00 1.00] 1.00 P [ 3.00] 3.00 D 2.50 Beta Electrons S [ 1.00 1.00] 1.00 P [ 3.00] 3.00 D 1.00<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Guess for atomic kind: Fe2 Electronic structure Total number of core electrons 10.00 Total number of valence electrons 11.50 Total number of electrons 21.50 Multiplicity triplet Alpha Electrons S [ 1.00 1.00] 1.00 P [ 3.00] 3.00 D 1.00 Beta Electrons S [ 1.00 1.00] 1.00 P [ 3.00] 3.00 D 2.50<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> How could I configure the &BS section to obtain an accurate description of my system?<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Thanks in advanced.<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Best,<o:p></o:p> </div> <div> Diego<o:p></o:p> </div> <div> <div> El martes, 30 de mayo de 2023 a las 13:31:11 UTC+2, Krack Matthias escribió:<o:p></o:p> </div> <blockquote style="border:none;border-left:solid #CCCCCC 1.0pt;padding:0cm 0cm 0cm 6.0pt;margin-left:4.8pt;margin-top:5.0pt;margin-right:0cm;margin-bottom:5.0pt"> <div> <div> Dear Diego<o:p></o:p> <o:p></o:p> Both keywords can be used to define the initial atomic states and the total magnetization of the system in conjunction with the MULTIPLICITY keyword.
