[molpro-user] Dipole moment calculation with CCSD

[Tatiana Korona]

Hi,

Provided that you use 2002.6, you should write

1)
hf
ccsd
expec

or

2)
hf
ccsd;core,0
expec

In the first case you have be Molpro default core orbitals and the 
expectation-type (nonrelaxed) 1st order properties are calculated.

In the second case (no core orbitals) expectation-type (nonrelaxed) and 
orbital-relaxed 1st order properties are calculated. Relaxation with core 
is not programmed for CCSD in Molpro.

You can save the CCSD density matrix by typing dm,record, e.g.
dm,4444.2
and use it e.g. in matrop.

Best wishes,

Tatiana
