Carlos Manuel,

The input you have given works for 2008.1 and also for 2009.1 with small
modifications to take account of input changes:

> diff 2008.1.mol 2009.1.mol
12c12,13
< geometry={nosym;ANGSTROM;
---
> symmetry,nosym
> geometry={
34c35,36
< geometry={nosym;ANGSTROM;
---
> symmetry,nosym
> geometry={

It appears from our records that your institution has downloaded 2008.1
already and has a current license for 2009.1, so please can I suggest
you run with a newer version of Molpro.

Best wishes,

Andy
