Density Matrix from XMS-CASPT2 calculation
Dear developers,
Is it possible to obtain density matrix and/or natural transition orbitals for the perturbatively modified CASSCF wavefunction from an (X/R)MS-CASPT2 calculation?

Re: Density Matrix from XMS-CASPT2 calculation
I think it should be in the caspt2.h5 file, if you add the "Properties" keyword. Note that this is just the DM at CASSCF (i.e. a mix of the input CASSCF states), and not the DM corresponding to the first order perturbed wave functions.
