39 RELATIVISTIC CORRECTIONS

There are three ways in MOLPRO to take into account scalar relativistic effects:

  1. Use the Douglas-Kroll-Hess or eXact-2-Component (X2C) relativistic one-electron integrals.
  2. Compute a perturbational correction using the Cowan-Griffin operator (see section 6.13).
  3. Use relativistic effective core potentials (see section 12).
