Parameters:

• name (str) –

  'ccsd' || etc.

  First argument, usually unlabeled. Indicates the computational method to be applied to the system.

• properties (List[str]) –

  \(\Rightarrow\) [] \(\Leftarrow\) || ['rotation', 'polarizability', 'oscillator_strength', 'roa'] || etc.

  Indicates which properties should be computed. Defaults to dipole and quadrupole.

• molecule (molecule) –

  h2o || etc.

  The target molecule, if not the last molecule defined.

Examples:

>>> # [1] Optical rotation calculation
>>> properties('cc2', properties=['rotation'])
