David and Jim,
Thanks. I am now using the ff94 charges.
However, the problem of two (reasonably different) conformations
minimizing into one, is still there.
Regards,

There is no such beast. Charge distributions for non-polarizable force
fields are the same as in ff94.
Please see the files in $AMBERHOME/dat/leap/cmd, or pp. 17-19 of the
Users' Manual.
