Expectation values

Is it possible to compute in MOLPRO the expectation value of the hamiltonian
between two arbitrary states?
What I'd like to do is to  find two electronic states of a molecule
(|1>,|2>) (with MCSCF) then  add a point charge to the molecule and compute
the matrix elements of the new hamiltonian between the previously defined
states: <1|H'|1>,<1|H'|2>,<2|H'|2>, where H' includes the perturbation due
to the point charge.

Many thanks in advance,
Shai Ronen
