CH₄: NMR Chemical Shifts, SAOP potential

Sample directories: adf/CH4_SAOP/

Computation of the NMR chemical shifts for CH₄, with the model potential SAOP.

Important: use SAVE TAPE10. This is necessary for SAOP, since the nmr program does not know about SAOP or other model potentials. On TAPE10 the SCF potential is written, which is read in by the nmr program.

Note: For SAOP one needs an all-electron basis set
