# The TAPE21 result file and TAPE10 of ADF must be present under those names for
# the NMR calculation
# The NMR program uses mostly only one input (block) key NMR. The subkeys
# specify what output is produced (OUT) and for which Nuclei the NMR data are
# computed and printed (NUC). See the ADF manual.

# == Relativistic spin-orbit ZORA ==


# Using Spin-Orbit implies that NOSYM symmetry must be used in the ADF
# calculation: the NMR program cannot handle symmetry calculations in
# combination with spin-orbit terms and will stop with an error message if you
# try to do so.
