   # Calculation of the spin-orbit (SO) coupled excitation energies of H2O using the 
   # Hybrid Diagonal Approximation (HDA).
   # Relevant in case hybrid XC functionals are used.
   # For HDA icw SO symmetry NOSYM is required.
   # For speed reasons one should not use a too large value for HDA_CutOff.
