Refinement using NoSpherA2, an implementation of
NOn-SPHERical Atom-form-factors in Olex2.
Please cite:
F. Kleemiss et al. Chem. Sci. DOI 10.1039/D0SC05526C - 2021
NoSpherA2 implementation of HAR makes use of
tailor-made aspherical atomic form factors calculated
on-the-fly from a Hirshfeld-partitioned electron density (ED) - not from
spherical-atom form factors.

The ED is calculated from a gaussian basis set single determinant SCF
wavefunction - either Hartree-Fock or DFT using selected funtionals
 - for a fragment of the crystal.
This fragment can be embedded in an electrostatic crystal field by employing cluster charges
or modelled using implicit solvation models, depending on the software used.
The following options were used:
   SOFTWARE:       ORCA 5.0
   PARTITIONING:   NoSpherA2
   INT ACCURACY:   Normal
   METHOD:         R2SCAN
   BASIS SET:      cc-pVTZ
   CHARGE:         0
   MULTIPLICITY:   1
