Hello Molpro users!
Have you tried to get frequencies at the EOM-CCSD level?
As to my knowledge, it is working only for the CCSD. During
the frequency evaluation, only the energy(1) is taken into account.
One can optimize structure at the EOM-CCSD level using option
variable,energy(2)

....
int
hf
ccsd;maxiter,60
eom,1.2
eompar,maxiter=60
optg
variable,energy(2)
....

What do you suggest to do to solve my problems? I appreciate your help.

Martina
