Please see http://www.molpro.net/info/current/doc/manual/node457.html to learn about adding a finite electric field to the one-electron hamiltonian to support, for example, numerical differentiation of analytical polarisabilities to give the hyperpolarisability.

I'm using the POLARI,DM,SM command and getting a table in the middle of the output from where it normally prints the second order properties, but I only want the ZZ,ZZ element of this. I've read that the only way you can define variables such as this is if the EXPEC command is used,but i'm not sure as to which keyword I should use with EXPEC that would correspond to ZZ,ZZ moment of the quadrupole polarizability, or if there is another way. A typical input file of mine is below.
