<div dir="ltr">Dear all,<br><br>I am doing some tests for NMR calculations  (orbital shielding and fermicontact 
(non-relativistic)) for molecules, with a large unitcell keeping 
periodicity. <br><br>I have compared the results with Gaussian-09. results using BLYP 
functional are in well agreement where as when I tried to use hybrid 
functional (PBE, B3LYP, BHandHLYP) the results are okay for hydrogen but
 for other atoms its deviating just randomly.<br><br>Any suggestion regarding this ? <br><br>or any explanation why BLYP functional preformed well and hybrid functional are showing so much deviation?<br>Shall I tune the functional part to match with Gaussian functional.<br><br><br>Kind regards<br>Arobendo <br><br><br><br><br>##################################################<br>@SET PROJECT_NAME molecule-NII-30-QZVP<br><br>@SET MULTIPLICITY 2<br>@SET BASIS_SET Ahlrichs-def2-QZVP<br><br>@SET BASIS_SET_FILE ~/Calc/pot-set/EMSL_BASIS_SETS<br>@SET POTENTIAL_FILE ~/Calc/pot-set/POTENTIAL<br><br>#####################################################################<br>&GLOBAL<br>  PROJECT ${PROJECT_NAME}<br>  PRINT_LEVEL LOW<br>  RUN_TYPE LINEAR_RESPONSE<br>&END GLOBAL<br>#####################################################################<br>&FORCE_EVAL<br>  &DFT<br>    UNRESTRICTED_KOHN_SHAM T<br>    MULTIPLICITY ${MULTIPLICITY}<br>    BASIS_SET_FILE_NAME ${BASIS_SET_FILE}<br>    POTENTIAL_FILE_NAME ${POTENTIAL_FILE}<br>    &MGRID<br>      CUTOFF 300<br>      NGRIDS 5<br>      &RS_GRID<br>        DISTRIBUTION_TYPE DISTRIBUTED<br>      &END RS_GRID<br>    &END MGRID<br>    &QS<br>      METHOD GAPW<br>    &END QS<br>    &SCF<br>      &OUTER_SCF<br>        MAX_SCF 2000<br>      &END OUTER_SCF<br>      SCF_GUESS RESTART<br>      MAX_SCF 2000<br>    &END SCF<br>    &XC<br>      &XC_FUNCTIONAL PBE<br>        &PBE<br>          SCALE_X 0.75<br>          SCALE_C 1.0<br>        &END PBE<br>      &END XC_FUNCTIONAL<br>      &HF<br>        &SCREENING<br>          EPS_SCHWARZ 1.0E-10<br>        &END SCREENING<br>        &MEMORY<br>          MAX_MEMORY  5<br>        &END MEMORY<br>        FRACTION 0.25<br>      &END HF<br>    &END XC<br>    &PRINT<br>      &HYPERFINE_COUPLING_TENSOR<br>      &END HYPERFINE_COUPLING_TENSOR<br>    &END PRINT<br>  &END DFT<br>  &PROPERTIES<br>    &LINRES<br>      MAX_ITER 1000<br>      RESTART_EVERY 5<br>      PRECONDITIONER FULL_ALL<br>      &NMR<br>      &END NMR<br>      &LOCALIZE<br>        MAX_ITER 1000<br>      &END LOCALIZE<br>      &CURRENT<br>        GAUGE ATOM<br>        ORBITAL_CENTER WANNIER<br>      &END CURRENT<br>      &PRINT<br>        &RESTART<br>        &END RESTART<br>      &END PRINT<br>    &END LINRES<br>  &END PROPERTIES<br>  &SUBSYS<br>    &CELL<br>      ABC 30.0 30.0 30.0<br>    &END CELL<br>    &COORD<br> H                 -2.07621800    1.84483700    0.57242200<br> H                 -0.92236600    1.16729100    1.69491600<br> H                  0.40979500    2.81871000    0.76978500<br> H                 -0.40978800    2.81864700   -0.76995500<br> H                  2.07624400    1.84478500   -0.57250400<br> H                  0.92240400    1.16720700   -1.69498000<br> H                  3.25735200   -0.36263200   -0.91316300<br> H                  2.46730500   -1.88166800   -0.43839100<br> H                  1.91905900   -1.01773300   -1.87691900<br> H                  1.90046000   -1.00477500    1.87349500<br> H                  2.85674100    0.42650100    1.44971600<br> H                  1.21613500    0.61381800    2.08323900<br> H                 -1.90050200   -1.00487600   -1.87340600<br> H                 -2.85680900    0.42638700   -1.44966800<br> H                 -1.21623900    0.61372100   -2.08326200<br> H                 -3.25733400   -0.36261200    0.91325600<br> H                 -2.46724900   -1.88165900    0.43859500<br> H                 -1.91898900   -1.01757700    1.87702700<br> C                 -1.12341800    1.31035900    0.62929400<br> C                  0.00001000    2.15905200   -0.00006300<br> C                  1.12343900    1.31031500   -0.62935800<br> C                  1.31903900   -0.08285700   -0.00271500<br> C                  2.30196900   -0.89185100   -0.86157000<br> C                  1.85035300   -0.00230300    1.44328300<br> C                 -1.31904800   -0.08284800    0.00272300<br> C                 -1.85040400   -0.00238300   -1.44323400<br> C                 -2.30192900   -0.89179600    0.86167800<br> N                  0.00000400   -0.79551200    0.00001000<br> O                 -0.00001300   -2.07424000   -0.00006200<br>    &END COORD<br>    &KIND  O<br>      LEBEDEV_GRID 100<br>      RADIAL_GRID 200<br>      BASIS_SET  ${BASIS_SET}<br>      POTENTIAL  ALL<br>    &END KIND<br>    &KIND  N<br>      LEBEDEV_GRID 100<br>      RADIAL_GRID 200<br>      BASIS_SET  ${BASIS_SET}<br>      POTENTIAL  ALL<br>    &END KIND<br>    &KIND  C<br>      LEBEDEV_GRID 100<br>      RADIAL_GRID 200<br>      BASIS_SET  ${BASIS_SET}<br>      POTENTIAL  ALL<br>    &END KIND<br>    &KIND  H<br>      LEBEDEV_GRID 100<br>      RADIAL_GRID 200<br>      BASIS_SET  ${BASIS_SET}<br>      POTENTIAL  ALL<br>    &END KIND<br>  &END SUBSYS<br>&END FORCE_EVAL<br><br><br><br></div>
