LBONE
LBONE = .TRUE. | .FALSE.
Default: LBONE = .FALSE.
Description: LBONE adds the small B-component to the chemical shift tensor.
LBONE restores the small B-component of the wave function inside the PAW spheres in the linear-response calculation of the NMR chemical shift tensor. The POTCARs used in VASP are scalar-relativistic and the AE-partial waves are solutions of the scalar-relativistic Kohn-Sham equation for the spherical atom. These have a large (A) and a small (B) component. The latter is not retained on the POTCAR, but approximately restored when LBONE=.TRUE.[1] This is done only in the one-center valence contributions to the chemical shift.
