# Spin-polarization constants W_ll' in Hartree.
# These numbers are NOT part of param_gfn2-xtb.txt, so real values must be
# supplied from a spin-polarized GFN parameter source before using --spinpol.
#
# Supported formats:
#   H  ss_value
#   C  ss sp pp sd pd dd
#   Fe ss sp sd ps pp pd ds dp dd
#
# Missing values are not silently set to zero. Use '-' only for shell pairs that
# are not present in the actual AO basis for the atoms in the system.
#
# Examples with placeholders, not production parameters:
# H  ss  <replace_with_value>
# C  ss  sp  pp  sd  pd  dd
