[molpro-user] frequencies at the uccsd level

[Kadir Diri]

Hello Molpro users!
I was wondering if Molpro can calculate numerically vibrational 
frequencies at the UCCSD level. I get the following error when I try to 
calculate the frequencies of water trimer cluster with an extra electron:

 CALCULATING HARMONIC VIBRATIONAL FREQUENCIES FOR UCCSD

 Incrementing variable O11XA  by +/- 0.010 BOHR
 ? Error
 ? Scan error
 ? The problem occurs in posinp

Thanks a lot in advance for any comments!
