The calculation of the magnitude of angular momentum <L^2> is not implemented. Until now there was no real interest in this property and it is not completely trivial to compute it, because L^2 is a two-electron operator.

The angular momentum operator, the vector (L_x, L_y, L_z), is implemented in codes for excited state because it is needed to describe the electronic circular dichroism.

It is not available for the ground state since TURBOMOLE works with real ground state wavefunctions. For those the expectation values for the components of L

are zereo (you see that from the definition of operators: for a real basis their matrix representation is purely imaginary and antisymmetric and their trace is thus zero).
