for defining basis sets, see mails to molpro-user by myself and Kirk
dated December 5 and 6, 2009. Unfortunately, there is not much
yet with RI basis sets (ri_basis) for transition metals. But it seems
Turbomole def2 JK fitting sets work quite well for this (and for
For the density fitting (df_basis) one can use the corresponding
Currently, CCSD(T)-F12 geometry optimizations are only possible using
numerical gradients (done automatically with optg, but expensive).
We are working on analytical gradients for MP2-F12 and CCSD(T)-F12,
but it will still take considerable time to finish this.
