LVGVCALC
LVGVCALC = .TRUE. | .FALSE.
Default: LVGVCALC = .TRUE.
WARNING: under construction. Description: LVGVCALC calculates the two-center contributions to the chemical shift tensor.
When performing a chemical shift calculation the standard pGv susceptibility[1] is calculated and used in the calculation of the CSA tensor. When LVGVCALC is true, the magnetic susceptibility is also calculated with the vGv approximation. Whether the vGv or pGv result is applied in the calculation of the CSA tensor is controlled by LVGVAPPL.
The vGv expression for the orbital susceptibility was introduced Ref.[2].
