[molpro-user] noncanonical orbitals in CCSD-F12

[Mariusz Radon]

Dear Colleagues:

Can anyone tell me whether the current implementation of CCSD-F12 in
Molpro is compatible with use of noncanonical orbitals, in particular
Kohn-Sham orbitals from preceding DFT calculations?

Many authors have used KS orbitals in coupled cluster calculations; they
can often be regarded as a cheap replacement of Brueckner orbitals. In
Molpro this approach works nice for "ordinary" CCSD, but how about
explicitly correlated (F12) calculations? Thank you in advance for your
reply.

Kind regards,
Mariusz Radon
